Sorry ladies, Joe Manganiello is off the market.

While on vacation in Italy the True Blood heartthrob, 33, popped the question to his girlfriend, actress/model Audra Marie, his rep tells PEOPLE.

Manganiello, who plays werewolf Alcide Herveaux on the HBO drama, and Marie met at a 2009 Super Bowl party, but it was anything but love at first sight.

"She wouldn't go out with me for six months," Manganiello told PEOPLE in September. "We started dating a few months before I got cast [on True Blood]."
