Shanna Moakler

Shanna Moakler and Gerard Butler were photographed getting cozy at the Hollywood opening of Shin nightclub on Monday.

Throughout the night, Butler also served guests drinks behind the bar.

At one point, a patron told him, “Thanks,” and he said, “I have no idea what the f–k I’m doing.”

When asked if he’s taken any ladies to lunch lately, Butler recently joked with Usmagazine.com, “Oh, you know, Jennifer Aniston, Cameron Diaz, Julia Roberts, Cindy Crawford – and I may even get together with a single one.”

His flirty behavior with Moakler comes days after her ex, Travis Barker, blogged that she hasn’t visited him in the hospital in L.A.
