Katy Perry and John Mayer Held Hands at Allison Williams' Wedding

They were holding hands, so is the on-again, off-again couple back together?

The couple was photographed holding hands over the weekend at the wedding of "Girls" actress Allison Williams and College Humor founder Ricky Van Veen in Wyoming.

"John and Katy looked happy," a source told People. "They held hands and sat next to each other during the wedding ceremony."

"I’m living in the now and not fantasizing about the past," Perry said at the time. "I have a lot of respect for [John] still, and I know it goes both ways. There’s no bad blood, but I’m sure there will be inspired songs."

Reps for both stars have not responded to requests for comment.
