Gerard Butler is keeping up his clean living after his stint in rehab, but it doesn’t mean he’s missing out on fun. Recently, the actor attended the Crash Kings concert at L.A.’s Troubadour. Butler appeared to arrive at the rock show solo – and he abstained from alcohol and stood in the back of the venue. Though he was on his phone for a good period of time, he was extremely polite and chatted with fans. He also made a little eye contact with a tall brunette during the show, according to a fellow audience member.
