The bad blood between Levi Johnston and Sarah Palin continues, as Johnston told the CBS Early Show Wednesday he's keeping secrets about the former vice presidential candidate that could do severe damage to her reputation.
"There are some things that I have that are huge," he said. "And I haven't said them because I'm not gonna hurt her that way. I have things that can, you know -- that would get her in trouble, and could hurt her. Will hurt her. But I'm not gonna go that far. You know, I mean, if I really wanted to hurt her, I could, very easily. But there's -- I'm not gonna do it. I'm not going that far."
A taste of Johnston's ammo includes an accusation he made in an earlier Vanity Fair article, claiming the politician would refer to her own child, Trig (who suffers from Down syndrome), as "retarded."
"I was just in shock for the first time I heard it," Johnston said. "And then she'd say it regularly. And I think she was joking, but it doesn't make it right."
Johnston said the "retarded" revelation was just the tip of the iceberg in terms of what he's keeping to himself about Palin.
"Those are just little things I put in Vanity Fair," he said. "You know, all the big things I got, I'm keeping -- you know, I'm keeping them in, and -- you know, it's just something that probably will never come out."
Johnston -- the 19-year-old father of Sarah Palin's grandson, who stood alongside the politician and her family on the platform at last year's Republican National Convention -- is reportedly spending lots of time in New York and Los Angeles in hopes of kick-starting a career in modeling. He's been pumping up lately, getting ready to shoot a nude spread for Playgirl magazine.
