Robert Downey Jr. The Letterman Show Sherlock Holmes Chaplin The Joker

Last night we snapped Robert Downey Jr. leaving Letterman in NYC, and the Sherlock Holmes star was looking oh so sexy in this blue pinstriped suit. Okay, so I'm not wild about the print, but look at the way it fits him! And that smile? I'm totally going to go see Guy Ritchie's latest flick!
