Nashville rockers Kings of Leon recently announced they’ll headline New York’s Madison Square Garden early next year, but on Wednesday night, they played their biggest U.S. show to date, performing in front of a sold-out crowd of over 7,000 at Los Angeles’ Nokia Theater L.A. Live. On hand to help them celebrate the achievement was a slew of celebrity fans who stayed long past the band’s 90-plus minute set. Among the famous faces jamming the backstage hallway: Drew Barrymore (who also attended the Kings’ New York show, where she was famously snapped making out with Gossip Girl’s Ed Westwick), Cameron Diaz, Mark Ruffalo, Liv Tyler, Strokes singer Julian Casablancas, Foo Fighters drummer Taylor Hawkins, and Reno: 911!’s Nick Swardson.
More unexpected were Zac Efron and girlfriend Vanessa Ann Hudgens, who spent most of the post-show hang adorably attached at the hip while showering endless praise onto brothers Caleb and Nathan Followill. Turns out Efron has a long history with the band: He met the Followills back when he was 14 at a family wedding he attended in Oregon, he told us, and has been a loyal follower ever since. Who knows, maybe the High School Musical star will turn up in a video the band is shooting this week for their next single, “Use Somebody.” It’s a performance-based clip to which friends, family, and longtime fans are strongly encouraged to attend. Efron seemed to fit the bill on all three counts.
