Sure, paparazzi can be invasive and annoying, but every once in a while they can also be quite informative.
Well, judging by this latest evidence, it seems the couple is, for now, still on.
The musical pair was spotted making the rounds out in New York last night on what seems like a fun-filled date night.
So what exactly do two superstar millionaires do for a night out?
Well, in John and Katy's case, the 34-year-old and 27-year-old, respectively, had dinner at Pearl restaurant before making their way to a private nightclub.
And despite his misbehavior in relationships past, Mayer certainly seems to be stepping up his game and acted the perfect gentleman, holding open the car and restaurant doors for Katy.
Katy, meanwhile, didn't leave too much to the imagination, rocking a super-sheer dress, black fedora and leather jacket for their night out.
Talk about a firework.
