Joe Manganiello Admits to Staring at Girlfriend Sofia Vergara's Butt!

Joe Manganiello shows off his large muscles in a tank as he heads to the gym on Wednesday (August 20) in Los Angeles.

The day before, the 37-year-old actor’s girlfriend Sofia Vergara showed off her assets in tight jeans at a tanning salon in Los Angeles.

Joe was recently asked by E! News if he really stared at his girlfriend’s butt in public several months ago as accused.

“Come on! You can’t put that in front of me,” Joe joked. “I’m not going to apologize. I totally got busted.”

“We didn’t start dating till she was single; she had a boyfriend at that time, so I probably could have gotten into a fight for doing that,” Joe added. “I’m not trying to start a fight at the White House, but if that walks in front of you, it’s like the Pied Piper.”
