Katy Perry's romance with John Mayer has fizzled.

People magazine reports the duo has split.

"They'll end up as friends," one source told the magazine. "They were honestly having fun. People made it out to be far more than it was."

But another source told Us Weekly, "She is making it seem like it wasn't serious with John, but she is hurt."

According to People, Katy and John had been dating for a couple of months, though the gossip sites caught on to their relationship only a few weeks ago.

The couple was spotted together at a Los Feliz house party, Hollywood hotspot Chateau Marmont and a Beverly Hills pool party.

Prior to her hook-up with Mayer, the former Mrs. Russell Brand dated Robert Ackroyd of the British rock band Florence + the Machine.

Mayer has been linked to a bevy of beauties including Taylor Swift, Jennifer Aniston and Jessica Simpson.
