Who is hotter, Sarah Palin or her daughter Bristol? 

Well, Levi Johnston definitely has an opinon and RadarOnline.com has the audio from a radio interview where he picked which one of the Palin women he’d rather have sex with.

On WLS Radio Chicago’s Roe Conn & Richard Reoper Show, radio legend Steve Dahl joined the crew and asked the 21-year-old Alaskan author of Deer In the Headlights “Who would you do?”

Levi Johnston’s bombshell new book makes many shocking claims about his baby momma, Bristol Palin’s famous family — among them — Sarah Palin had a ‘cougar crush’ on the hunky 24-year-old Alaskan native!

“Even growing up my friends would always say that [Palin would flirt with me], it seems kind of weird. Then one of my publishers said she had a cougar crush on me! I guess I'd say, 'Yeah, I think she did.' Now looking back and remembering what everyone said. She never touched me or anything like that! Now it kind of weirds me out thinking about it," Levi told E! News in an exclusive interview.

Another startling claim made by the Playgirl pin-up is that he and and his ex-fiancée planned their pregnancy.  “Bristol wanted to have a baby," he says, contradicting the Palins' side of the story. "It all happened on purpose. I wasn't tricked into it...I kind of went with it."

With the release of his new book, Levi Johnston is taking shots at his baby mama Bristol Palin and her controversial family, sending zingers towards the checkered story that the Alaskan political family has proclaimed to be the truth about his relationship with his then teenage girlfriend.

Deer in the Headlights is Levi’s side of the story, and he’s been telling a very different vdersion than Bristol’s of how, when and why she got pregnant with their son Tripp. 

“Bristol was on birth control for a long time,” Levi told The Huffington Post. “She got off it soon after Trig [Sarah Palin's son] was born. I think Trig was a big motivator for her. Her mother just had a child and I think Bristol was really jealous. She was the one who was supposed to have that kid and that's when she got off of [birth control]. We weren't practicing safe sex and she ended up getting pregnant.”
