Who's that boy? Social Networker and Gossip Girl romancer Armie Hammer. Bam!!!

Social Network hottie and big tall drink of baking soda Armie Hammer stopped by Chelsea Lately, and Ms. Handler teased him. A bunch. Why? 'Cuz one of her male staffers is wayyyy man-crushy all over him. Who can blame him? Hammer is tall, talented, darn fine-looking, funny, charming and... HE'S GOT REALLY BIG FEET.

And take note: He's playing a big gay who was J. Edgar Hoover's man-pony in the upcoming biopic, J. Edgar, starring opposite Leonard DiCaprio.

And he's looking cute in GQ this month, too. If you like fashiony man photos.

WATCH!

And here's the Hammer looking clean-cut in GQ. Awwwwwww...
