Robert Pattinson stepped out with friends to see The Black Keys perform at The Sayers Club in Hollywood on Sunday.
Dressed casually in a blue button-down, short-sleeved shirt and a backwards baseball cap, Pattinson arrived just before the show started at 9 p.m.
Despite the drama surrounding his relationship with Twilight costar Kristen Stewart, Pattinson couldn’t have looked happier as he chatted with male pals including The Master actor Rami Malek, an onlooker tells PEOPLE.
“He had a smile plastered across his face during the entire show,” the source adds. “He bobbed his head to almost every song. When he wasn’t rocking out he sipped on beer and spent time texting.”
After the show ended at 10 p.m., the Cosmopolis star stayed at the club, enjoying beers and posed for photos with 98.7 deejay Kennedy.
“Pattinson seemed amused by her and was laughing a lot throughout their conversation,” the source says.
