In 1984, Le Beauf auditioned for the role of the eldest Huxtable daughter Sondra on "The Cosby Show". 26 years old at the time of her audition, she was initially considered too old to play one of the children, being only 10 years younger than Phylicia Rashad, the actress who played her mother, Clair Huxtable. Pop singer Whitney Houston also auditioned for the same part, but Le Beauf's theater experience won her the role. Sabrina went on to play Sondra Huxtable for all eight seasons of "The Cosby Show", from 1984 through the series' end in 1992. Sondra, a Princeton graduate that went on to marry and start a family of her own, was a popular character on the show; in 1988, 50 million viewers turned in to watch Sondra give birth to twins, named Winnie and Nelson in honor of Nelson Mandela and his wife.
