'Secret Life': Bristol Palin talks abstinence and safe sex, but not Levi Johnston

Possibly the most famous unwed teen mother, Sarah Palin's daughter Bristol Palin, is making a cameo appearance on the ABC Family series, " The Secret Life of the American Teenager" Monday (July 5).

The Dish Rag got a chance to chat with Bristol, who is an abstinence spokesperson, and "Secret Life" star Francia Raisa, (who plays Adrian) about the show and the depiction of the realities of teen pregnancy.
