John Krasinski was on Late Night yesterday and he challenged Jimmy Fallon to a game called Lip Sync-Off. Basically the two men lip sync a song and who ever does it better is the winner. Well at first it started off slow, but the The Office star finished it off in a big way. His last song was Boyz II Men’s I’ll Make Love to You and he serenaded the NBC late night host with it. It was so sexy that now I think Emily Blunt is one very lucky woman to have him as a husband!
