Worst: Paula Abdul Pre-Judges Song, Season 7
Throughout her nine seasons on American Idol, Paula Abdul was the subject of many jokes and much speculation about whether she was intoxicated. And her double-vision critique of Jason Castro in Season 7 didn't help matters. A visibly flustered — and somewhat slurred — Abdul said she liked his first song, adding that his second left her "a little empty" as the crowd snickered and host Ryan Seacrest and the Top Five contestants looked bewildered. When Randy Jackson pointed out that the contestants had only sung one song so far, Simon Cowell rolled his eyes as Abdul exclaimed, "This is hard!" She later blamed the gaffe on seeing him perform the other tune during rehearsal and getting confused.
