They're hot then they're cold, they're yes then they're no...

Pop princess Katy Perry's on-again, off-again romance with seductive singer John Mayer seemed to be very much on as of Sunday evening in New York City, where the hit-making couple blew off steam at Pearl Restaurant and Soho House, and we've got the pics for you right here on Breaking Celebrity News.

The 27-year-old Firework singer was sexier than ever in a get-up consisting of a sheer lace olive dress, black boots, a hat and a black leather jacket.

The Daughters singer, 34, wore a denim shirt, tan jeans and a navy blue jacket; his body language was that of the perfect gentleman, holding doors open for his lady love.

Katy, since her marriage to Russell Brand, briefly dated Florence + The Machine guitarist Robert Ackroyd before hooking up with Mayer, the ladies' man who's dated Minka Kelly, Taylor Swift, Jennifer Aniston and Jessica Simpson, among others.
