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.”

Congratulations, Sarah Palin is a grandma for the second time!

The former Vice-Presidential candidate is the proud grandma of a brand new baby girl RadarOnline.com has learned, the daughter of her oldest son Track and his wife Britta.

A source close to the family confirmed the arrival of the little girl to the young parents who were just married just three months ago in May.
