LOL! Joe Manganiello was caught by photographers checking out now girlfriend Sofia Vergara's butt at the White House Correspondents' Dinner on May 3.

In the flashback pic, the Modern Family star is talking to her costar Jesse Tyler Ferguson, his husband Justin Mikita, Gravity director Alfonso Cuaron and his girlfriend Sheherazade Goldsmith. Lingering in the background is the True Blood hunk, who (without shame) is taking in Vergara's famed assets.

Us Weekly exclusively broke the news on July 7 the pair are now officially an item and, indeed, first met that evening at the White House Correspondents' Dinner. Vergara was still engaged to Nick Loeb at the time; the pair split earlier this year.

"That's the first time Sofia and Joe met," the insider tells Us. Another source adds, "Sofia is Joe's dream girl! He's been smitten with her for years. He's always had a huge crush on her. Things are going well for them so far."

Way to go, Joe!
