Bristol Palin makes her acting debut on tonight's ABC Family drama series, The Secret Life of the American Teenager.
But don't expect her to line up any more acting gigs in the future.
Asked if she wants to pursue an entertainment career, she tells UsMagazine.com, "Not acting. I like doing speaking engagements and stuff like that. Right now I'm just focused on raising Tripp," her 2 1/2-year-old son with Levi Johnston.
Still, Palin, 19, says she was happy to film the episode of Teenager.
She appears as a friend of Amy (Shailene Woodley) at a music program for teen mothers in New York.
"I didn’t have many lines or anything like that," says Palin. "I just hope that this show opens up a dialogue between parents and teens -- and teens amongst themselves -- about the consequences of teen pregnancy, sex in general and relationships."
To see her acting debut, tune into The Secret Life of the American Teenager on ABC Family tonight at 8 p.m. ET/PT.
