Robert Pattinson parties with the Black Keys Robert Pattinson stepped out Sunday evening in Hollywood for a show by rockers the Black Keys. Making a guys' night of it, Pattinson rolled with friends including his "Breaking Dawn - Part 2" costar Rami Malek for the exclusive show, hosted at the Sayers Club by 98.7 FM. Ducking into a rear entrance close to 9 p.m., Pattinson, in a black baseball cap and jeans, posted up against against a back wall and enjoyed mixed drinks as the band played hits including "Tighten Up." PHOTOS: KStew and RPattz through the years Rob sang along to virtually every track, breaking occasionally to greet folks such as Sayers Club creative director Jason Scoppa. The young actor reportedly has reconciled with Kristen Stewart, his "Twilight Saga" costar and longtime off-screen love, following her July indiscretion with director Rupert Sanders. But Sunday wasn't about his relationship, it was about music. Rob seemed relaxed, positioned behind the rows and rows of fans snapping photos and taking video, not of him but of the band. An unusual experience for Pattinson, but perhaps a typical night at the exclusive venue.
