In typical blunt no-nonsense Simon style, the acerbic Brit vowed that he will “never work with Ryan again” and revealed that the defining moment that decided his departure from Idol was when he was stuck next to Seacrest on a long haul flight, while he was singing out of tune listening to Miley Cyrus’ Party In The USA - six times over! According to Simon, he thought at that moment, “I actually can’t do this for much longer,” but he was just jesting – we hope!

Simon went on to say that he will “miss the fun” of recording the twice weekly live show and shared that his favorite performance ever was “when Fantasia sang Summertime.”

Simon also said that he loved his time working with co-judge Randy Jackson, but confessed, “I never eveer understood a single word he said – I never know if he’s complimenting some-one or not!”
