Bella Thornton is the youngest daughter of actor, filmmaker and musician Billy Bob Thornton and his wife, Connie Angland. Born in Los Angeles in September 2004, she has largely grown up outside the Hollywood spotlight and, as of 2026, is a college student at California Polytechnic State University in San Luis Obispo.
Although Bella is frequently searched because of her famous father, reliable information about her is more limited than many online biographies suggest. Billy Bob Thornton has spoken publicly about their close relationship, her education and her childhood interests, but Bella herself maintains a comparatively private life. There is also an important source of confusion online: professional credits belonging to another woman named Bella Thornton have sometimes been incorrectly attributed to Thornton’s daughter.

Who Is Bella Thornton?
Bella is the fourth and youngest of Billy Bob Thornton’s children and his only child with Connie Angland. Her arrival was reported by the Associated Press in September 2004, when Thornton and Angland announced the birth of their daughter in Los Angeles.
Unlike her father, Bella has not built a public career in entertainment. Most of what is reliably known about her comes from interviews Thornton has given over the years, particularly when discussing fatherhood, family life and the way his relationship with his daughter has influenced his acting.
That distinction matters because some online profiles describe Bella as an actress, screenwriter or filmmaker. Available evidence does not reliably support those professions for Billy Bob Thornton’s daughter.
How Old Is Bella Thornton?
Bella Thornton is 21 years old as of September 16, 2026. The strongest available evidence points to September 22, 2004, as her date of birth.
There is some disagreement online about the exact day. IMDb has listed September 24, 2004, but that date conflicts with contemporary reporting: an Associated Press report announcing Bella’s birth was published on September 23.
More recent evidence supports September 22. In a 2025 Esquire profile, Thornton discussed protecting September 22 and the surrounding travel days in his schedule so that he would not miss his daughter’s birthday. For that reason, September 22 is better supported than the September 24 date repeated by some databases.
Bella Is Billy Bob Thornton and Connie Angland’s Only Child Together
Bella’s father, Billy Bob Thornton, has had a wide-ranging career as an actor, writer, director and musician. His major film credits include Sling Blade, A Simple Plan, Monster’s Ball and Bad Santa, while television audiences also know him from series including Fargo, Goliath and Landman.
Her mother, Connie Angland, has worked behind the scenes in the film industry, including special-effects and puppetry-related work. Thornton and Angland were already together when Bella was born in 2004.
The couple eventually married in October 2014, approximately a decade after their daughter’s birth. Their family life has generally remained less visible than Thornton’s earlier celebrity relationships.
Bella Thornton Has Three Older Half-Siblings
Bella is the youngest of Billy Bob Thornton’s four children. Her three paternal half-siblings are Amanda Brumfield, William Thornton and Harry Thornton, who were born during earlier relationships in their father’s life.
Because of the age differences and Thornton’s multiple marriages and relationships, online descriptions of the family can occasionally become confusing. Bella is Connie Angland’s daughter with Thornton and the youngest member of his four-child family.
She has not publicly built her identity around her siblings or family connections. Most mainstream coverage of the Thornton children has instead appeared in profiles explaining Billy Bob Thornton’s family history.
What Was Bella Thornton Like Growing Up?
One of the more revealing details Thornton has shared about Bella concerns her childhood fascination with nature.
When she was nine, he told PEOPLE that his daughter was particularly interested in insects and wanted to become an entomologist, a scientist who studies insects. Butterflies and caterpillars were among the creatures that fascinated her.
The detail has become more interesting with time because Bella later pursued biology at college. It would be speculative to suggest that she intends to become an entomologist today, but her current studies show that science remained part of her academic interests as she grew older.
Books also appear to have remained important to her. Thornton’s later comments about her university life indicate that she has maintained interests spanning both science and literature.
Where Does Bella Thornton Go to College?
Bella attends California Polytechnic State University, San Luis Obispo, commonly known as Cal Poly.
Her enrollment is particularly well documented because Cal Poly itself published a feature about Thornton being a university parent in April 2026. The university identified Bella as a sophomore at the time.
Thornton explained that the family explored several possibilities after she finished high school. They visited institutions including UCLA before Cal Poly emerged as the right choice for Bella.
Her father has since developed his own connection to California’s Central Coast through his visits. In discussing Bella’s experience at the university, he also mentioned the campus library as one of the places she particularly enjoyed.
What Is Bella Thornton Studying?
According to Billy Bob Thornton, Bella is studying biology and English.
Esquire reported the combination in its November 2025 profile of the actor, when Bella was described as a 21-year-old college sophomore.
The two subjects offer a useful glimpse into interests that Thornton had discussed much earlier in his daughter’s life. Her biology studies have an obvious connection to the childhood fascination with insects that he described years ago, while English complements the interest in reading he has also associated with her.
There is no reliable public evidence establishing what career Bella plans to pursue after university. Describing her as a future scientist, writer or entertainment professional would therefore go beyond what she or her family has publicly confirmed.
Billy Bob Thornton Has Spoken Openly About Their Close Relationship
Although Bella rarely speaks publicly about her father, Thornton has repeatedly discussed what being her parent means to him.
Their relationship received renewed attention during promotion for Landman, the Paramount+ drama in which Thornton plays Tommy Norris. His character is the father of a daughter, Ainsley Norris, played by Michelle Randolph, and Thornton explained that his real experience as a protective father helped him understand that part of Tommy’s personality.
He has described being particularly protective of Bella while also recognizing the need to let her make her own decisions as she becomes an adult.
The importance he places on their relationship also affects his professional schedule. Esquire reported in 2025 that Thornton keeps time around Bella’s September birthday clear when arranging his work commitments. The same profile noted that her name is tattooed on his arm.
These details provide considerably more insight into their relationship than speculation about Bella’s private life, which she has largely kept away from public view.
Has Bella Thornton Appeared in Public With Her Parents?
Bella has occasionally accompanied her parents to public events, particularly when she was younger, but she has never maintained the type of regular red-carpet presence associated with a celebrity career.
Family coverage has documented appearances with Thornton during her childhood. She was seen at entertainment events with Billy Bob Thornton and Connie Angland, and Getty Images archives include photographs of the family at premieres.
These appearances made her recognizable as Thornton’s daughter without turning her into an independently active Hollywood personality.
As she has grown older, the available reporting has focused much more on college and her father’s comments about their relationship than on entertainment-industry appearances.
Is Bella Thornton an Actress, Writer or Filmmaker?
There is no sufficiently reliable evidence that Billy Bob Thornton’s daughter has established a professional career as an actress, screenwriter or filmmaker.
This is one of the most important distinctions to make because Google results for “Bella Thornton” combine information about at least two people with the same name.
A separate Bella Thornton has a documented career as a writer and filmmaker. Her professional biography describes growing up in Sandy, Utah, attending Columbia College Chicago from 2019 to 2023, and training through organizations including The Second City and the Royal Academy of Dramatic Art.
That Bella has also been associated with screen projects including The Rabbit Hunters and received recognition through Stowe Story Labs. Final Draft and institutional sources independently document work by a filmmaker of that name.
Those accomplishments should not automatically be attributed to Billy Bob Thornton’s daughter.
Why Are the Two Bella Thorntons Being Confused Online?
The timelines provide the clearest warning.
Billy Bob Thornton’s daughter was born in 2004 and was publicly identified as a Cal Poly sophomore during the 2025–26 academic period. The filmmaker Bella Thornton’s professional biography, by contrast, says she attended Columbia College Chicago from 2019 through 2023, while her FilmFreeway profile lists a February 26, 2001 birth date.
Those details do not describe a coherent single educational timeline.
The confusion has nevertheless spread to entertainment and biography databases, and some secondary websites have combined Billy Bob Thornton’s family information with the filmmaker’s education, writing credits and professional achievements.
For readers searching specifically for Billy Bob Thornton’s daughter, the reliable record is much narrower: she is a Cal Poly student whose publicly reported academic interests include biology and English. No verified evidence currently establishes that the film and screenwriting credits associated with the other Bella Thornton belong to her.
Does Bella Thornton Have a Boyfriend or Husband?
Bella’s current relationship status is not publicly confirmed.
There is no reliable mainstream reporting establishing that she has a husband, fiancé or publicly known partner. Given that she has not chosen to maintain a highly public personal profile, unsupported claims about her relationships should be treated cautiously.
The same principle applies to many details commonly found on celebrity biography sites. A lack of public information does not establish whether someone is single or in a relationship; it simply means that information has not been reliably made public.
Is Bella Thornton on Instagram?
No verified personal Instagram or other official social-media account belonging to Billy Bob Thornton’s daughter could be confidently established from reliable public sources.
Searches for her name can lead to accounts and professional profiles belonging to other people, including the filmmaker with the same name. Those profiles should not be presented as Bella’s official accounts without independent confirmation.
Her relatively limited online presence is consistent with the broader pattern of her life: she is publicly known through her family but has not developed a prominent personal celebrity platform.
What Is Bella Thornton’s Net Worth?
Bella Thornton’s personal net worth has not been credibly established.
Specific figures published by celebrity biography or net-worth websites lack the type of financial evidence needed to treat them as reliable. Her father’s wealth should not be assigned to her, either.
Because Bella does not have a verified public business or entertainment career from which meaningful financial estimates could be made, giving a dollar figure would create a misleading impression of precision.
What Is Bella Thornton Doing Now?
The most recent substantial public information about Bella concerns her education.
As of April 2026, Cal Poly identified her as a sophomore at its San Luis Obispo campus. Thornton had previously told Esquire that she was studying biology and English.
Her college life has also influenced where her parents spend their time. Speaking about becoming a Cal Poly dad, Thornton described the family’s positive experience with San Luis Obispo and California’s Central Coast.
Beyond those details, Bella continues to maintain considerable privacy. There is no verified announcement of an entertainment career, business venture or other major public professional project.
Conclusion
Bella Thornton is best known publicly as Billy Bob Thornton and Connie Angland’s daughter, but she has largely chosen a life outside her father’s Hollywood spotlight. The most reliable recent information places her at Cal Poly, where Thornton has said she studies biology and English.
Her father has spoken warmly about their close relationship and the importance of remaining present in her life as she enters adulthood. Claims describing Bella as an established actress or filmmaker should be approached carefully because they appear to conflate her with another professional who shares her name.
