Joe Manganiello showed off one lucky lady on Thursday night, when he made an appearance at an event in Beverly Hills.

The Magic Mike star stopped by a private residence to attend the Samsung Galaxy S III launch, where he arrived with a “tall, leggy blonde on his arm,” an onlooker tells PEOPLE. “His date was usually by his side throughout the whole night.”

At one point in the evening, the pair was “canoodling and definitely getting cozy,” the source says.

But Manganiello, who seemed like he was “in a great mood,” also devoted time to chat with some other celebrities at the party. Ashlee Simpson, Anna Kendrick and a pregnant Anna Faris were among the other famous attendees.
