This week's Celeb, Jon Hamm, is best known for his role as Don Draper on the TV Show "Mad Men." We really fell in love with Don and wished ourselves back in the the 1960s so we could hang out with him and dress like Betty! But Jon is also a hilarious comedian! Jon has guest starred on 30 Rock and SNL and you can see him more recently in the hit comedy, Bridesmaids!

We think Jon is so hot, and the funny thing is that Mad Men creator, Matthew Weiner almost didn't cast him because of his looks. Matthew thought Jon was too handsome (haha, so true) and later decided, "it was perfect to cast sort of the perfect male in this part." And we totally agree!
