Kathy Hilton Bio
Kathleen Elizabeth Hilton (née Avanzino; born March 13, 1959) is an American socialite, fashion designer, actress, and television personality whose career has spanned more than five decades. She first stepped in front of the camera as a child performer in the late 1960s before transitioning into fashion, business, and reality television. Hilton is widely known as the mother of socialite Paris Hilton and fashion designer Nicky Hilton, as well as the half-sister of actresses Kim and Kyle Richards. Since 2011, she has also been a familiar face on The Real Housewives of Beverly Hills, where she joined the cast in a recurring role and became a fan favorite.
Beyond her family connections, Hilton has built a reputation as an entrepreneur, launching her own party-dress line, a signature skincare range, and a fragrance. She has remained a steady presence in Hollywood circles, balancing small-screen cameos with high-profile brand partnerships.
Early Life and Background
Kathy Hilton was born on March 13, 1959, in Manhattan, New York City. She is the daughter of Kathleen Mary Dugan and Larry Avanzino, with Italian roots on her father’s side and Irish heritage on her mother’s side. Her parents later divorced, and her mother married Kenneth E. Richards. From that marriage Hilton gained two maternal half-sisters, Kim and Kyle Richards, both of whom would go on to become reality television stars in their own right. Hilton also has five paternal half-siblings from her father’s remarriage.
After her family moved west, Hilton attended Montclair College Preparatory School in Los Angeles, where she graduated and formed a close friendship with Michael Jackson. The two remained close friends until his death in 2009. Her teenage years in Los Angeles placed her near the heart of the entertainment industry and helped shape her early interest in performing.
Path to Celebrity
Hilton began working as a child actress in 1968, when she was just nine years old, taking on small television roles and film parts throughout the early 1970s. Her early credits included appearances on Nanny and the Professor, Bewitched, Family Affair, Happy Days, and The Rockford Files, as well as film roles in The Dark and On the Air Live with Captain Midnight. These performances gave her a foundation in front of the camera while still in her teens.
By 1979, Hilton stepped away from acting to focus on her personal life, marrying businessman Richard Hilton that same year. She later returned to the public eye through fashion, opening The Staircase, a gift and antiques store on Sunset Plaza in Los Angeles, during the 1980s and early 1990s. Her transition from child performer to entrepreneur set the stage for her later work on television and in design.
