Pictures of Simon Cowell Jet Skiing Shirtless in the Caribbean

The X Factor host made big news in 2010 when he announced that he was leaving American Idol, and we'll get to see the results of the shake-up when the show returns in just a few weeks. Simon's frequent willingness to show off his abs also earned him a spot on yet another year-end list — 2010's most memorable shirtless guys.
