Simon Cowell showed off his impressive muscles while taking a spin on a jet ski yesterday in the Caribbean. The late entry to sexy shirtless guys of the year and highest earning man in primetime seems to be enjoying a well-deserved vacation before the return of American Idol on Jan 12. Ellen DeGeneres joins Simon at the judging table this season, which was one of our biggest headlines of the year. One thing Simon isn't celebrating this holiday season is the number one spot on the UK charts — for the first time in four years, the newest The X Factor winner was beat out, and many were disappointed to see the top honors go to Rage Against the Machine instead.
