It was an action-packed afternoon on the set of White Collar in NYC today. True Blood's Joe Manganiello left his werewolf alter ego back in Bon Temps, LA, and yielded a gun for an intense looking shoot-out alongside series regular Tim Dekay. It's been an exciting few week for Joe with True Blood premiering its fourth season on Sunday and Joe's shirtless GQ spread. You can catch more of Joe this Summer on his HBO drama, but you'll have to wait until January to watch his White Collar episode. Matt Bomer managed to keep himself out of harms way while bullets were flying, though he did slip into a perfectly tailored suit for his own batch of scenes. Tiffani Thiessen had a special visitor on the set as well, taking a break with daughter Harper Smith who just turned 1 on June 15.
