Levi Johnston told E! News that he believes Sarah Palin had a "cougar crush" on him.

Like Joe McGinniss' tell-all-book The Rogue, Levi Johnston's newly released book, Deer in the Headlights: My Life in Sarah Palin's Crosshairs, depicts Sarah Palin in an unflattering light. The 21-year-old sat down with E! News to talk about Palin's major crush and his former girlfriend's widely talked about teen pregnancy.

"Even growing up my friends would always say that [Palin would flirt with him], it seems kind of weird. Then one of my publishers said she had a cougar crush on me!" Johnston said.

“I guess I'd say, 'Yeah, I think she did.' Now looking back and remembering what everyone said.”

When directly asked if Sarah Palin have a cougar crush on him? He claimed to have no idea but when asked if he were a betting man, he answered, "I wouldn't bet on it, I'd say yeah. Looking back and knowing what everybody's been telling me from day one, I'd say yeah."

However, Johnston added, "She never touched me or anything like that!"

In addition to discussing his book, the young dad explains fatherhood was no accident and that Bristol Palin wanted to have a baby after mom Palin gave birth to Trig. In offsetting Sarah and Bristol Palin's version that the pregnancy was unplanned, Levi told E! News, "Bristol wanted to have a baby."

Johnston admitted to going along with plans of the baby and marriage plans.

The E! News interview with Johnston is slated to air tonight at 7 p.m. ET and 11:30 p.m. ET.
