Sarah Palin rips into arch-nemesis Levi Johnston after he calls her son "retarded."

Soon to be full frontal in Playgirl Levi popped a cap in the ex Alaska Gov on CBS Early Show where he repeated that Palin often referred to her Down’s Syndrome afflicted child, Trig, as "retarded".  Levi also said Palin has done worse and knows things that could get her "in trouble and could hurt her.

"You know, I mean, if I really wanted to hurt her, I could very easily" Levi said. " But there’s – I’m not gonna do it."

Levi who was engaged briefly to Palin’s daughter Bristol who bore his child has been been duking it out with her mother all over the media for months.

And now Sarah has roared back, slamming her once and never son-in-law.

"Consider the source of the most recent attention-getting lies," Palin said via a flack. "Yet Those who would sell their body for money reflect a desperate need for attention and are likely to say and do anything for even more attention."

Yet Palin’s memoir Going Rouge streets next month and she received $1.25 million in advance while still in office as governor.

Sarah also slammed CBS for interviewing Levi. "CBS should be ashamed for continually providing a forum to propagate lies."

Who wants to bet she’ll be on a lot of CBS Shows to promote HER book?

"I stand by my story 100 percent and everything in it’s the truth" Levi countered today.
