Not only were some lucky people treated to a private Black Keys concert at Sayers Club in LA on Sept. 30 — they also got a glimpse of Robert Pattinson!

“It was a private show for 98.7 FM, and Rob showed up," an eyewitness tells Life & Style. "He was in a great mood and definitely wasn’t trying to hide or blend in or anything. He came with a few friends and was smoking one of those electronic cigarettes."

The 26-year-old, who posed with 98.7 FM show host Kennedy (see inset, above), didn't seem to have much on his mind aside from having a good time.

"He knew almost every song performed and was loving the whole set — bobbing his head, holding up his drink every now and then and clapping and cheering." the eyewitness says. "He sang along to a few lyrics. He definitely looked like he was having fun."
