Donald Trump has a score to settle with former Miss CA USA Carrie Prejean.
Trump, the head of the Miss USA Organization, disputes the claim that Prejean makes in her book "Still Standing: The Untold Story of My Fight Against Gossip, Hate, and Political Attacks" -- that the Donald divided up pageant contestants based on looks.
"Carrie should be ashamed of herself," Trump tells "Extra" of the 22-year-old ex-beauty queen. "Certainly I would never do a thing like that, because it would be too hurtful. I don't stand the ones that are less attractive to one side, and the beautiful ones on the other side. It was total nonsense -- it was fiction in her imagination... I don't even know how she came up with an idea like that."
He adds, "She should not have written that in the book."
Trump also commented on Prejean's confirmation that she made an erotic tape for an ex-boyfriend -- a racy tape that Carrie calls the "biggest mistake of my life."
"She's trying to act like she's a nun... so maybe she should release the sex tape and people would see whether or not she is a nun," Donald tells "Extra."
At the end of the day, Trump chalks up Carrie's revelations to self-promotion.
"She's trying to sell a book," Trump explains. "She's doing the best she can... I can't imagine too many people would be interested in it, but you never know what sells these days."
