Levi Johnston Spills All about Sarah Palin

Levi Johnston, the father of former Republican Vice Presidential candidate Sarah Palin's grandson, is going on the record about what he knows about Palin and her family.

Johnston, who welcomed son Tripp almost a year ago with Palin's teen daughter Bristol, tells Mark Steines that the public Palin is very different from the private one: "The TV side of Sarah Palin which I am telling you is not the real Palin. She goes out and puts on a big show for you and that is the Palin you know."

He explained that Palin used some surprising terms to describe her son Trig, born with Down Syndrome. Johnston says, "She'd come in from work and she'd be like, 'Hey, where is my retarded baby,' and just something like along those lines. The kids, Bristol and them, didn't think much of it, but the first time I heard it, I was in shock, I didn't know what to say. So, but then she, it kind of became a normal thing for her to say and you know, I guess, but she'd always have a smile on her face, laughing about it."
