Levi Johnston says Sarah Palin knew he, Bristol were having sex

Washington, Apr 4 (ANI): Bristol Palin's former fiancé and babydaddy Levi Johnston has revealed that Sarah Palin knew he and her daughter were having sex when they lived under her roof.

In a show airing April 6, Johnston tells Tyra Banks: "I'm pretty sure she probably knew. Moms are pretty smart."

While on the show, Levi talked about his sex life on national television, reports People.

However, the show hasn't been received well by the Palin household.

After taking on The Tyra Banks Show, Johnston was hit with a blistering response from the Alaska Governor.

"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," says the statement from the Palin family rep.

"Bristol's focus will remain on raising Tripp, completing her education, and advocating abstinence," the statement continues. 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," the statement concluded.

Levi and Bristol, who were high school sweethearts, planned to wed after graduating - but ended up splitting earlier this year. At the time, Johnston told Good Morning America that he needed to mature before getting married. (ANI)
