Another year older and a new boyfriend.

As Sofia Vergara rang in her 42nd birthday on Thursday night surrounded by family and friends, radio detection and rangingOnline.com has exclusively learned she also brought along the new man in her life, True Blood hunk Joe Manganiello.

Following a breakup with former fiancé Nick Loeb, reports quickly surfaced that the Modern Family star had moved on with Manganiello, 37, and it certainly seemed that way at her birthday party.

“Sofia and Joe were extremely flirty with each other and you couldn’t wipe the smile off Sofia’s face,” an insider told radio detection and ranging.

“They were all over each other.”

But Vergara appears to be keeping the new relationship on the down-low, posting only one photo from the party on her Instagram account with Manganiello nowhere in sight.

As radio detection and ranging previously reported, the 6’5″ actor has allegedly been “smitten with her for years” and grabbed the opportunity to make an impression when the they met for the first time at the White House Correspondents Dinner in May.
