Looks like things are really heating up for these two!
The Dark Horse singer was spotted at the Marlton Hotel in NYC on Thursday, leaving with Diplo in tow!
But they weren’t ready to call it a night, and they left for Skylight at Moynihan Station where the Amazing Spider-Man 2 after party was going on.
"Diplo and Katy were super affectionate. It's a really fun relationship for them both, easy and casual."
Take this one slow, KP! We’d hate to see your heart get broken again!
But who knows, maybe this will be the relationship that lasts!
