Clay Aiken thinks Rihanna couldn't win American Idol

When asked which current pop star couldn't make it through "American Idol," Clay Aiken pretty much said all of them. "Oh God, there's too many. Too many ... Current pop singer? I've stopped listening to them because they can't sing." But then he decided to drop the diplomacy and single out Rihanna. "Rihanna has some pitch problems for sure. She does." As a contestant on "Celebrity Apprentice," Clay is refreshingly upfront with his team, and he was equally blunt when talking about getting facial liposuction done during a jaw surgery. "I was like, you know what, I'm already down [on the operating table], go ahead and take the vacuum in there and suck the fat out of my chin." At least Honest Aiken is as hard on himself as he is on everybody else.
