The actor, 26, and some famous celebrity friends hit Bootsy Bellows in West Hollywood. There, Efron laid low, sipping on Fiji water in the club’s back VIP room as pals Robert Pattinson, Ryan Rottman and Joe Jonas joined him, an onlooker tells PEOPLE.
“Zac looked happy and relaxed and wanted to talk with his friends,” the onlooker says. “He didn’t care about who else was at the club or any of the other nonsense going on.”
When Jay Z and Kanye West’s hit "Otis" came on, Efron (who maintained his sobriety) bobbed to the beat with 28-year-old Pattinson (who sipped cocktails) while being very chatty with the rest of the group.
And where was Rodriguez during the guys’ night?
