What is Brittny Gastineau's net worth?

Brittny Gastineau is an American model and television personality who has a net worth of $500 thousand. Brittny Gastineau is best known for starring in the early 2000s reality TV series "Gastineau Girls" alongside her mother, Lisa Gastineau. The show, which aired on E! Entertainment Television from 2005 to 2006, followed the mother-daughter duo's lives in New York City. She has also appeared on "Filthy Rich: Cattle Drive," "Keeping Up with the Kardashians," "The Hills," and "Cribs." Brittny's father is retired NFL player Mark Gastineau.

Early Life

Brittny Gastineau was born on November 11, 1982, in New York City. She is the daughter of Lisa Gastineau and former New York Jets defensive end Mark Gastineau, one of the most famous and flamboyant NFL pass rushers of the 1980s. Her parents' marriage and divorce were both highly publicized, and Brittny spent much of her childhood living primarily with her grandmother.

She attended Clarkstown High School North in New City, New York. After graduating, she enrolled at the University of Alabama. Although she initially moved south for college, her interest in fashion, modeling, and entertainment eventually drew her back to Manhattan. That decision put her at the center of the New York fashion and celebrity world just as reality television was beginning to turn socialites and celebrity children into mainstream stars.

Modeling Career

After returning to New York, Gastineau signed with Elite Model Management through its celebrity division. Her modeling career gained momentum quickly, including a magazine spread for "Stuff" that helped introduce her to a wider audience.

She soon moved into runway work, walking for designers including Anne Bowen and Anna Sui during New York Fashion Week in 2005. She also modeled for Yumi Katsura's bridal collection and walked for the avant-garde fashion brand Heatherette. Her look and social profile made her a natural fit for the celebrity-driven fashion era of the mid-2000s.

Gastineau also appeared on the covers of magazines including "Steppin' Out," "Hamptons," "Social Life," and "Lucire," with additional features in publications such as "L.A. Confidential" and "Life & Style." Her commercial work included beauty and fashion partnerships with brands including L'Oréal Paris, MAC Cosmetics, and Ed Hardy.

"The Gastineau Girls"

In 2004, Brittny and her mother, Lisa, landed a development deal with E!, which led to the 2005 premiere of "The Gastineau Girls." The series followed the pair as they navigated New York society, dating, fashion events, and Brittny's attempt to establish herself as a model.

The show ran for two seasons and became part of the same reality television wave that later produced a much larger celebrity-family ecosystem. In hindsight, "The Gastineau Girls" was an early example of the format that would become a staple of entertainment television: glamorous family dynamics, personal branding, fashion access, social drama, and aspirational lifestyle content.

Brittny's on-screen chemistry with her mother was the center of the series. Their close, sometimes theatrical relationship gave the show its identity and remained a defining part of Brittny's public image.

Other Television and Media Work

Gastineau also appeared on the E! reality series "Filthy Rich: Cattle Drive," which followed the children of celebrities as they adjusted to life on a working Colorado cattle ranch. The show leaned into the contrast between privilege and physical labor, placing Brittny and other young social figures far outside their usual environments.

She later made guest appearances on "Keeping Up with the Kardashians," helped by her long-running friendship with Kim Kardashian. Gastineau also appeared on "The Hills," "Cribs," and "Top This Party." Her media work expanded into hosting as well, including appearances on "The View" and segments for Fuse TV and Spike TV. In 2009, she made a brief cameo in the Sacha Baron Cohen comedy "Bruno."

Fashion, Jewelry, and Art

Brittny and Lisa Gastineau extended their mother-daughter brand into fashion and accessories. They co-created the luxury accessory line Tresu Glam and later moved into jewelry with "Gastineau Glamour," a vintage-inspired, bohemian collection that they launched on HSN.

In later years, Brittny shifted more of her professional focus toward art. Based in Los Angeles, she has worked as an art curator and broker, while also writing about travel, fashion, and art world subjects for "Haute Living." That transition gave her career a more mature second chapter, moving beyond the early-2000s reality television spotlight into a world built around taste, collecting, and cultural access.
