It appears that Katy Perry and John Mayer have rekindled their romance.

After splitting twice in less than a year, the chart-topping pair was reportedly spotted packing on the PDA on Monday in New York City at the Waldorf Astoria.

According to People, Katy and John attended Monday's Friars Foundation Annual Applause Awards Gala honoring Don Rickles, where John played.

"When John performed, Katy was enamored by his performance," a source told the mag. "He sang 'One for My Baby (and One More for the Road).' When they were sitting down, she had her arm around John at one point. They shared kisses."

And that wasn't the only PDA the pair displayed at Monday's event.

"[They] were seen smooching and rubbing one another's backs. They were affectionate towards one another - very lovey-dovey," another source told the mag.

Following the show, Katy and John were spotted exiting the Waldorf Astoria together.

Earlier this month, Katy opened up about her feelings for the rocker, telling Vogue, "I still am madly in love with him."

In April, John told Ellen DeGeneres that "coupling is a tricky thing."

Katy, 28, and John, 35, previously dated during summer of 2012, before splitting (for the first time) in August 2012. They first began dating after her divorce from Russell Brand, which was finalized in February 2012.
