Kathy Hilton Net Worth: Family and Relationships Guide

Full Name: Kathy Hilton ·
Spouse: Rick Hilton ·
Children: 4 (including Paris Hilton) ·
Occupation: Socialite, fashion designer, actress, television personality

Six confirmed biographical points, one clear pattern: the Hilton family fortune sits at the core of nearly every conversation about Kathy Hilton.

What is Kathy Hilton’s net worth?

Kathy Hilton’s net worth is a topic of constant public curiosity, largely because no single number has been officially confirmed. According to multiple entertainment outlets, her combined household wealth with husband Rick Hilton — an heir to the Hilton Hotels fortune — is estimated at $350 million (SCMP (Hong Kong media), Parade (entertainment magazine)). This figure makes her the wealthiest cast member ever to appear on The Real Housewives of Beverly Hills, according to SCMP.

Kathy Hilton’s family wealth

The Hilton hotel empire, founded by Conrad Hilton, provides the base of the family fortune. Rick Hilton, Kathy’s husband since 1979, is the grandson of Conrad Hilton and a real estate investor in his own right (Parade (entertainment magazine)). Kathy herself comes from a well-connected family; her mother was a successful actress and her father a producer.

Real estate holdings

The couple owns multiple properties, including a Bel Air mansion and a beachfront home in Malibu. While the exact values are not publicly recorded, real estate analysts estimate their portfolio runs into the tens of millions. The Hilton family also has significant holdings through Hilton Grand Vacations and other hospitality ventures.

The implication: the $350 million figure is the most reliable estimate for the Hilton household, but it masks the individual contributions.

Who is richer, Kathy Hilton or Kyle Richards?

This comparison dominates conversations about the Richards sisters. Kathy Hilton, as noted, carries a reported combined net worth of $350 million. Kyle Richards, her half-sister and a full-time cast member of RHOBH, is estimated at $100 million when combined with her husband, real estate agent Mauricio Umansky (Parade (entertainment magazine)). That puts Kathy ahead by a wide margin.

Kathy Hilton’s financial standing

Kathy’s wealth is primarily inherited through marriage. Rick Hilton’s share of the Hilton hotel fortune — estimated at several hundred million — is the main driver. Kathy also earns from occasional TV appearances, a fashion line (a collaboration with Nicky Hilton), and social appearances.

Kyle Richards’ income sources

Kyle’s net worth of $100 million comes from her long-running role on Real Housewives, acting credits in films like Halloween (the 2018 reboot), and her husband’s real estate firm, The Agency. She has also launched a clothing line and a home-decor collection. Still, even Kyle’s combined wealth falls short of Kathy’s household figure.

The pattern: when comparing Hilton and Richards, the key differentiator is the scale of inherited wealth versus earned income.

Do Kyle Richards and Kathy Hilton have the same mother?

Yes — and no. The family tree of the Richards sisters requires a careful look. Kathy Hilton (born 1959) and Kyle Richards (born 1969) share the same mother, Kathleen Richards. However, they are half-siblings: Kathy’s father was Lawrence Avanzino, while Kyle’s father was Ken Richards (Wikipedia, Wikiwand (online encyclopedia)).

The Richards family tree

Kathleen Richards married Lawrence Avanzino and had Kathy. After divorcing, she married Ken Richards and had two daughters: Kim (born 1964) and Kyle. So Kathy, Kim, and Kyle all share the same mother. Kim and Kyle share both parents; Kathy is their older half-sister.

Kathy and Kyle’s relationship

On Real Housewives, Kathy and Kyle appear close, often seen vacationing together and supporting each other’s events. But tensions have surfaced — notably in Season 11 of RHOBH, when a heated argument erupted over Kathy’s alleged comments about Kyle’s marriage. The sisters have since reconciled publicly, though the dynamics remain a topic of fan speculation.

Who’s richer, Kathy Hilton or Lisa Vanderpump?

Lisa Vanderpump, a former RHOBH cast member and star of Vanderpump Rules, has an estimated net worth of $90 million (Parade (entertainment magazine)). Her wealth comes from a string of successful restaurants (Vanderpump Las Vegas, Pump, SUR) and TV production deals. Kathy Hilton’s $350 million combined net worth is roughly four times larger.

Kathy Hilton’s wealth

As covered, Kathy’s net worth is anchored in the Hilton hotel fortune. Even if we consider only the portion attributable to Rick Hilton, it dwarfs the typical reality-TV income stream. Kathy’s own earnings from TV appearances and endorsements add modestly to the pile.

Lisa Vanderpump’s wealth

Lisa has built a mini-empire from scratch — a sharp contrast to Kathy’s inherited wealth. She owns 8 restaurants, has a wine label (LVP Sangria), and earns production fees from Vanderpump Rules. Her $90 million is almost entirely self-made.

The catch: while Kathy’s wealth is larger, Lisa’s net worth is a direct reflection of her own business acumen.

Is Kathy Hilton still friends with Lisa Vanderpump?

The friendship between Kathy Hilton and Lisa Vanderpump has been a recurring subplot on RHOBH. The two have appeared together at events and on the show, but the official status of their relationship is not publicly confirmed.

History of their friendship

Kathy and Lisa were part of the same social circle long before Kathy joined the show as a “friend of.” Lisa has said in interviews that she enjoys Kathy’s company and respects her as a mother and businesswoman.

Recent interactions

In 2023 and 2024, the two were seen together at Beverly Hills charity galas and posted friendly Instagram photos. However, no joint interviews or definitive statements have been made. The bond appears cordial but not deep.
