Teen Mom Bristol Palin Urges Kids Not to Have Sex

Bristol Palin and her 15-month-old son Tripp appear in a new Candie's Foundation PSA advocating against teen pregnancy.

"What if I didn't come from a famous family?" asks Palin, who welcomed Tripp in December 2008 when she was just 18 years old, as cameras flash to photos of her on the campaign trail of her with former Vice Presidential nominee mom Sarah Palin. (She has since split from fiance Levi Johnston.)

"What if I didn't have all these opportunities?" she asks again. "Believe me, it wouldn't be pretty."

The ad's message: "Pause before you play," she says somberly.

Bristol will also advocate abstinence when she plays herself in ABC Family's The Secret Life of the American Teenager this summer.

"I am thrilled to be on this show and to be a part of a program that educates teens and young adults about the consequences of teen pregnancy," Palin said.
