Former child star Kim Richards has been on United States TV screens since the age of seven, from her role as the adorable Prudence on "Nanny and the Professor" to appearing alongside her sister Kyle on the reality program "The Real Housewives of Beverly Hills. " The sister of Kathy Hilton, and thus the aunt of famed socialites Paris and Nicky Hilton, Richards started her career alongside Juliet Mills and Richard Long in the 1970s family sitcom "Nanny and the Professor." Her talent and cute charisma helped her win the part of sister Sandy Hunter on the teen drama "James at 16" and a recurring role as the daughter of Mr. Drummond's old friend on the hit sitcom "Diff'rent Strokes." Meanwhile, she starred in Disney's beloved "Witch Mountain" movies, playing a teen with paranormal powers who is on the run with her twin brother. She closed off her '70s run playing the teen daughter of McLean Stevenson's divorcée character on the sitcom "Hello, Larry." Until 1985, Richards bounced from cameos on prime-time dramas to starring in features like the teen drama "Tuff Turf," opposite a young James Spader. She essentially retired from the screen after marrying G. Monty Brinson in 1986, though she returned in 2006 to appear as the estranged mom of Christina Ricci's character in the drama "Black Snake Moan" and to join her sister Kyle on "The Real Housewives of Beverly Hills" at the end of 2010.
