Are Katy Perry And John Mayer Back Together?

The singers have once again sparked romance rumors after attending Los Angeles' FYF Fest together.

After reportedly breaking off their brief romance in late August, Katy Perry and John Mayer have been spotted together again in the wake of the breakup news.

The two were spotted on Saturday at FYF Fest in Los Angeles. In one photo posted by a fan, the on-again, off-again, on-again couple were spotted standing side by side taking in the music. They also took a group shot with their friends, including Perry's bestie, "Raising Hope" actress Shannon Woodward.

According to an E! News source, in addition to dancing they were also "stealing kisses" during the show.

According to photos posted on Just Jared, they were also together at the Little Door Restaurant in L.A Tuesday night.

Perry and Mayer kicked off romance rumors in June, when they were reportedly spotted hanging out at SoHo House in West Hollywood. They were finally photographed together in August leaving the famed Chateau Marmont in Los Angeles. And, while a source told Us that Perry was "really upset about" the August split, the twosome looked to be back on better terms this week. No one from either camp has commented on any of the romance rumors
