On Monday night, the duo reunited (again!) for a romantic evening in NYC. Katy, 28, stunned in a peach Sally LaPointe satin gown, while John, 35, looked handsome and pulled-together in a well-fitting gray suit as the pair were snapped leaving the Waldorf Astoria Hotel.
Earlier in the evening, John performed at the Friars Foundation Awards Gala. A source told E! News the "Paper Doll" singer arrived solo, and Katy arrived after the event had already started and joined John's table.
"Seated at the table with them, amongst others, were Whitney Cummings, John Stamos, and Joan Rivers," added a source. "Other celebrities in attendance at the event like Louis C.K., Jeffrey Ross, and Bob Saget, seemed to be flocking over the John and Katy's table."
But the cutest part? Katy and John were "affectionate" and "very lovey-dovey," an insider told ABC News. "They were smooching and rubbing one another's backs…And Katy had her arm around John at one point."
Katy and John were also "cuddly and cute" on their NYC date night on Saturday, a source told E! News. The pair hit up the Greenwich Hotel and the Bowery Hotel and, according to a source, "definitely gave the impression that [they] are 100 percent back together."
E! News broke the news earlier this month that John and Katy were "back on,", although sources at the time claimed the pair were "not putting a label on it.'
Hey, whatever you want to call them, it looks like John and Katy are having fun!
