Kathy Hilton is far more than just a Hollywood socialite—she’s a savvy businesswoman, former actress, fashion designer, and philanthropist, boasting a combined net worth of $350 million with her husband, real estate magnate Rick Hilton. While many recognize her as the mother of Paris and Nicky Hilton, Kathy has carved out her own successful path over the years.
Now 65 (born March 13, 1959), her journey has been remarkable, spanning from childhood acting roles to helming a luxury fashion brand and making appearances on reality TV. Let’s take a closer look at her impressive career, accomplishments, and multimillion-dollar real estate ventures.
From Child Star to Hilton Heiress
Before becoming part of the renowned Hilton family, Kathy Hilton (née Kathleen Elizabeth Avanzino) was already making a name for herself. Born in New York City, she moved to Los Angeles following her parents’ divorce. After her mother remarried, Kathy became the half-sister of reality TV personalities Kim and Kyle Richards, best known for their appearances on The Real Housewives of Beverly Hills.
Kathy also became a fan favorite on The Real Housewives of Beverly Hills. While her half-sisters, Kim and Kyle Richards, were main cast members, Kathy initially made occasional guest appearances before officially joining as a “friend of the housewives” in Season 11. Her sharp wit, extravagant lifestyle, and comedic moments quickly won over audiences. However, in June 2023, she announced her departure from the show for good.
Beyond television, Kathy has also built a successful career in fashion. Since 2012, she has designed the Kathy Hilton Collection, a line of sophisticated party dresses available at high-end retailers like Neiman Marcus, Saks Fifth Avenue, and Nordstrom. Her impeccable style even earned her and her daughters, Paris and Nicky, a feature in Vogue in 2020, where they showcased pieces from Valentino’s 2021 resort collection.
The Hilton Family & Next-Gen Wealth
Kathy and Rick Hilton share four children: Paris, Nicky, Barron, and Conrad Hilton. As of 2025, their family has grown to include seven grandchildren—three from Nicky’s marriage to James Rothschild, two from Barron, and two from Paris, who welcomed her little ones with husband Carter Reum.
With a combined fortune of $350 million, the Hiltons lead a life of luxury, owning multiple homes across the U.S. However, Kathy is known for more than just her glamorous lifestyle—she has a generous heart for philanthropy. A dedicated supporter of the Make-A-Wish Foundation, she has also been honored by the Starlight Children’s Foundation for her charitable efforts alongside her daughters.
The Hiltons’ High-End Real Estate Moves
The Hilton family’s real estate portfolio is nothing short of spectacular. Here are some of their most notable investments:
- Hamptons Mansion: In 1999, Kathy and Rick purchased a seven-bedroom estate in Water Mill, New York, for $3.385 million. They frequently rent it out during the summer for $300,000 to $400,000 per season. In February 2024, they listed the property for nearly $15 million.
- Bel-Air Estate: The couple bought a mansion in Bel-Air for $9.2 million in 2015, later demolishing it to construct a more lavish home. Originally listed for $55 million in 2021, they ultimately sold it in January 2024 for $25 million to Chinese billionaire Zong Qinghou.
- The Pierre Hotel Apartment: In 2014, they added a city retreat to their collection, purchasing a $2.5 million apartment in the iconic Pierre Hotel in New York City.
