In March Steven Tyler explained his fears that he would swear on live television if he got excited about a performance on American Idol.
Fast forward six weeks and his prediction came true in spectacular style when he dropped the F-bomb after an energetic routine by contestant Casey Abrams.
The Aerosmith frontman, 63, couldn’t control himself after witnessing Casey in full flight on the talent show.

He told the singer: ‘You already are a cult hero, I mean there’s millions of people in America that are really angry, because you p***** them off because you’re so f****** good.
‘You changed so many peoples’ minds. I gotta tell you, I love you man.’
Fellow judges Jennifer Lopez and Randy Jackson couldn’t believe what they were hearing and desperately tried to stop Tyler before he unleashed any more profanity.
