“Thank you San Francisco! I had fun!!!” the 30-year-old singer, who performed at the event, tweeted.

Adam recently opened up to MTV News about his latest album, Trespassing.

“On this album I co-wrote most of the songs on it, so I was in the studio writing, and creating these songs from the ground up,” he shared. “Creating is the best part of this whole job.”
