Trump Takes Aim at Britney and Rosie

Donald Trump is joining the list of critics who are slamming Britney Spears' VMA performance, calling it "disgraceful."

"I caught Britney's performance on the VMAs," Trump said. "It was disgraceful. I think it was sad and I hope she can pull it together...Britney has to shape up and she has to shape up fast."

Trump also took aim at his public enemy, Rosie O'Donnell, and her upcoming book "Celebrity Detox."

He blasted, "Rosie is a loser and her book is terrible. She attacks Barbara Walters and she attacks me...she's not a smart person. If her book does as poorly as her magazine and Broadway shows, it will fail."

There are rumors today that Rosie does, indeed, have a few words for her former "View" co-host Walters.

Though Walters told "Extra" yesterday, "Rosie sent me the book with a note telling me how much she loved me," Rosie is hinting otherwise.

New York's Page Six says Rosie writes in the book that Barbara, 77, should retire, saying, "At some point, a person gets tired. It's inevitable...everyone has to go. Going is part of the gig."

She also supposedly writes, "I would be less-than-honest if I were to say that there is no trouble between Barbara and I. I mean, our differences are obvious."

When a fan asked Rosie on her blog if some pages had been leaked, Rosie wrote, "It looks like it. They printed some of it."
