Katy Perry, John Mayer celebrate his birthday in NY

Katy Perry and John Mayer are still going strong.

Mayer, who counts Jennifer Love Hewitt, Jessica Simpson, Minka Kelly, Taylor Swfit and Jennifer Aniston among his famous past loves, celebrated his 35th birthday on Tuesday.

He and Perry, 27, were spotted grabbing lunch at ABC Kitchen in New York City's West Village, and they got more dressed up —- as you can see here —- for a night out at The Box in the Big Apple.

Last month, the two were spotted out and about in Los Angeles as reports surfaced that Perry had fallen "dangerously in love" with the musician. But they were said to have broken up in August before reconnecting in September.

Maybe Mayer, who has been recovering from throat surgery, has finally found true love?

Look for them, or at least Mayer, to show up in Charleston this weekend. According to his website, Mayer will be sitting in with the Zac Brown Band at the Southern Ground Music & Food Festival.
