Early Life & Education

Kathleen Elizabeth Avanzino was born on March 13, 1959, in Manhattan, New York City, to Kathleen Mary Dugan and Larry Avanzino. Her paternal grandfather was of Italian descent, while her mother’s side was Irish and Scottish. Her parents’ marriage was turbulent—her mother, later known as “Big Kathy,” was a notorious stage mother and social climber who allegedly used aggressive tactics to secure her family’s future.

After her parents divorced, Kathy’s mother married Kenneth E. Richards, a retired lieutenant colonel and successful ladies’ clothing developer. From this marriage, Kathy gained two maternal half-sisters: Kim Richards and Kyle Richards, both of whom would later become actresses and stars of The Real Housewives of Beverly Hills. Kathy also has five paternal half-siblings from her father’s remarriage.

Kathy attended Montclair College Preparatory School in Los Angeles, where she formed a lifelong friendship with Michael Jackson. The two remained close until his death in 2009, with Kathy later recalling their innocent bond as teenagers in the entertainment industry.

Career Journey

Child Acting Career (1968–1979)

Kathy began working as a child actress at age 9, appearing in some of the most beloved television shows of the era. Her credits include:

  • Nanny and the Professor (1970)
  • Bewitched (1971)
  • Family Affair (1971)
  • Marcus Welby, M.D. (1971)
  • Sigmund and the Sea Monsters (1974)
  • Happy Days (1977)
  • The Rockford Files (1978)

She also appeared in films including The Dark (1979) and On the Air Live with Captain Midnight (1979). At 15, around the time she met Rick Hilton, she effectively retired from acting to focus on her future as a wife and socialite.

Business Ventures (1980s–Present)

In the 1980s and early 1990s, Kathy operated The Staircase, a gift and antiques store on Sunset Plaza in Los Angeles. She later transitioned to television commerce:

  • 2002: Debuted merchandise sales on QVC
  • 2007: Launched a signature skincare line on HSN
  • 2008: Released “My Secret” perfume
  • 2012–present: The Kathy Hilton Collection of party dresses, sold in 400+ stores worldwide including Neiman Marcus, Saks Fifth Avenue, and Nordstrom

In December 2020, Kathy, Paris, and Nicky modeled Valentino’s 2021 resort collection for Vogue. In September 2021, she appeared in Oscar de la Renta’s New York Fashion Week campaign.

Television Career and RHOBH (2003–Present)

Kathy made select appearances on The Simple Life (2003–2005), starring her daughter Paris. In 2005, she hosted I Want To Be a Hilton on NBC. She also appeared on The World According to Paris (2011).

Her most significant television role began in October 2020, when she joined The Real Housewives of Beverly Hills as a “friend of the housewives” for Season 11. She quickly became a fan favorite, with People calling her “already a Real Housewives of Beverly Hills legend.” Her quirky humor, accidental comedy (including asking Kyle what channel RHOBH aired on), and genuine family drama made her must-watch television.

The Aspen breakdown controversy of Season 12, where Lisa Rinna alleged Kathy had a meltdown at a nightclub, became one of the show’s most explosive storylines. Kathy denied the allegations and publicly stated she would not return if Rinna remained. In June 2023, she confirmed her departure from the series after two seasons, though she made a special guest appearance at the Season 13 reunion in January 2024.

In 2025, she appeared on Denise Richards & Her Wild Things in the episode “Yes, Chef!”

Philanthropy

Kathy’s charitable work is extensive. In 2007, she raised money for the Make-A-Wish Foundation by asking celebrities to auction belongings. In 2011, she and her daughters received an award from the Starlight Children’s Foundation. Her causes include The Race to Erase MS, City of Hope, The Junior League, Princess Margaret Cancer Centre, and the Alzheimer’s Association.

Personal Life

Marriage to Rick Hilton

Kathy met Richard “Rick” Hilton at a party when they were teenagers. Rick, the grandson of Hilton Hotels founder Conrad Hilton, was two years her senior. They married on November 24, 1979, when Kathy was 20 and Rick was 23—a union that has now lasted nearly 47 years.

Rick launched Hilton & Hyland real estate brokerage in 1993 and later Hilton Hilton with son Barron in 2024. Despite the famous last name, Kathy clarified on RHOBH that Rick has no current relationship to the Hilton Hotels chain.

Kathy and Rick have eight grandchildren total, with Nicky and Barron contributing the most. Kathy frequently shares photos of “Papa” Rick surrounded by his grandchildren on Instagram.

The Secret to a 47-Year Marriage

Kathy has been remarkably open about her marriage formula. In September 2024, she told People: “We have not been away from each other for two weeks in [all our] years of marriage.” Her rules include:

  • Always make up before bed
  • Never go to sleep without saying “I love you”
  • Keep a little mystery
  • Keep it exciting and fun
  • Respect and honesty above all

Their go-to date spot is The Cheesecake Factory—a surprisingly modest choice for a couple worth $350 million. Rick celebrated Kathy’s 65th birthday in 2024 with an Instagram post calling her “the best wife ever.”

Family Dynamics and “Big Kathy”

Kathy’s relationship with her mother, “Big Kathy” (Kathleen Dugan Avanzino Richards Catain Fenton), was complex. Big Kathy was a notorious stage mother who allegedly pushed her daughters into show business and taught them to “marry rich.” She was married multiple times and was described by biographer Jerry Oppenheimer as a “man hunter.” Kathy has spoken about her mother’s difficult legacy while maintaining that she was also a loving figure.

Her relationship with half-sisters Kim and Kyle Richards has been dramatized extensively on RHOBH, with Kathy often positioned as the peacemaker—or, depending on the season, the instigator—of family conflict.

Controversies

The Aspen nightclub incident of 2022 remains Kathy’s most public controversy. Lisa Rinna alleged that Kathy had a breakdown, made disparaging comments about cast members, and threatened to “destroy” Kyle. Kathy denied everything, and the feud escalated through the Season 12 reunion. Kathy’s ultimatum—that she would not return if Rinna stayed—effectively ended her full-time RHOBH tenure.

She has also faced scrutiny over her family’s wealth and privilege, particularly regarding the Hilton dynasty’s complicated history. However, Kathy has generally maintained a Teflon-like ability to deflect serious scandal.
