Los Angeles: Actor Gerard Butler was seen enjoying a dance with a mystery brunette at the Coachella Music Festival in Palm Springs and it seems he did not care about being seen out and about.

"The two were grinding like they were at a middle school dance. He didn`t seem to care who was watching," a source told nypost.com. The 42-year-old stayed sober at the event.

Emma Roberts, Zoe Kravitz, Paris Hilton and Emile Hirsch were seen enjoying the glamorous bash, reports contactmusic.com.
