Legendary rocker Bob Dylan twice tried to sneak into tapings of American Idol in disguise, according to the talent show's co-judge Paula Abdul. The Hurricane singer donned a fake beard in a bid to try and go unnoticed during the recording of the reality TV hit's fourth season in 2005 - but Abdul spotted him. The Straight Up singer says, "He (Dylan) had a beard and tried to be in disguise. But I knew it was him."
