American Idol season two runner-up Clay Aiken recently appeared on Andy Cohen’s show Watch What Happens Live! The brutally honest singer had quite a bit to say about present-day artists. During a segment called ‘Plead the Fifth,’ Cohen asked, “What current pop singer wouldn’t make it past the first round on American Idol?” Aiken responded, “There are too many. Too many. I’ve stopped listening to them because they can’t sing. I’m not gonna plead the fifth, I’ve just got to think for a minute. He then added, “Rihanna has some pitch problems.” The Battleship actress/pop singer has yet to respond to the remarks. If you have any ideas on who the others might be, comment below — which pop singer do you think would be voted off American Idol?
