Levi Johnston, Bristol Palin's ex-fiance, kisses and tells on Tyra

Levi Johnston, Britol Palin's ex-fiancee and father of her baby boy, talked to Tyra about his relationship with Bristol.  He said that the couple practiced safe sex "most of the time" and that their baby Tripp was probably conceived as a result of some sort of "wardrobe malfunction."  He also said that Sarah Palin must have known about their sexual relationship, because "moms pretty are smart," and he and Bristol sometimes shared a bedroom.

Here's a preview:

How did Sarah Palin respond to news of Levi's chat with Tyra?  Um, we guess you could say she was slightly pissed.    She released this statement through a family representative:

Bristol did not even know Levi was going on the show. We're disappointed that Levi and his family, in a quest for fame, attention, and fortune, are engaging in flat-out lies, gross exaggeration, and even distortion of their relationship.

Bristol's focus will remain on raising Tripp, completing her education, and advocating abstinence.  It is unfortunate that Levi finds it more appealing to exploit his previous relationship with Bristol than to contribute to the well being of the child.

Bristol realizes now that she made a mistake in her relationship and is the one taking responsibility for their actions.

Levi's comments could be damaging to Sarah Palin, who promotes abstinence only education and is expected to run for office again in the future. If she knew that her own teen daughter was sexually active while insisting that abstinence only education works, well, some voters might feel that she's got some 'splainin' to do.

The show will air on April 6.
