"The group was smoking cigars and bowling and dancing, having a fun time!" a source said. "Channing was dancing to the music they had playing in the Spare Room...that bowling area is pretty small and most of the guys were huge!"

The insider added that among all the partying, Bomer, himself, looked pretty spiffy.

"I mainly saw Joe bowling," the source said. "I think I saw Matt Bomer bowl once. He was in glasses and a little sweater/button-down combo. So gorgeous! There were older ladies there swooning over Channing, watching him."

Manganiello is engaged to actress Sofie Vergara.

Bomer previously opened up to People on how he doesn't want his kids, Kit Walker and Henry, to get involved in the entertainment business just yet since they still have a lot of childhood left.

"When I was eight-years-old, I asked my parents to get my head shots, and they were like, 'What are you talking about?! Go outside and play!' I'm so glad they did," the actor said. "I had a normal childhood where I was able to cultivate my own creativity, and I don't think I would have been ready for this crazy business at eight-years-old."
