Lisa Diane Whelchel (born May 29, 1963) is an American actress, singer, and writer best known for her role in the television series The Facts of Life as the preppy and wealthy Blair Warner.
Whelchel was born in Littlefield, Texas, the daughter of Jenny (née French), a real estate agent, and Jimmy Whelchel, an electrician. Lisa is the older sister of Cody Whelchel and Casey. She was raised for most of her childhood in Fort Worth, Texas and got her start as a Mouseketeer on The New Mickey Mouse Club, which aired in syndication from 1977-1978.
An original cast member of The Facts of Life, Whelchel once refused a storyline that would have made her character the first among the four young women in the show to lose her virginity in that episode. Having become a Christian when she was 10, Whelchel refused because of her Christian convictions, and the storyline was rewritten for the character of "Natalie." Whelchel appeared in every episode except that one.
