Rihanna dissed by Clay Aiken on 'Watch What Happens Live'

"Celebrity Apprentice" competitor and "American Idol" runner-up Clay Aiken said singer Rihanna wouldn't make it past the first round of "Idol" on Tuesday's (March 27) "Watch What Happens Live."

"Rihanna has some pitch problems for sure," he told host Andy Cohen during a game of Plead the Fifth.

He also said that if forced to "marry, screw or kill" Simon Cowell, Randy Jackson or Ryan Seacrest, he would kill Cowell.

"I would probably screw Ryan and marry Randy," he said.

Aiken also confessed to a little plastic surgery -- some liposuction on his chin -- when having work done on his jaw to remedy TMJ pain.

Do you think Aiken was right about Rihanna?
