Katy Perry and John Mayer
The fireworks have fizzled for Katy Perry
and John Mayer
The pop star, 27, and crooner, 34, who were linked
this summer, are no longer dating, a source confirms to PEOPLE.
"They'll end up as friends," the source says. "They were honestly having fun. People made it out to be far more than it was."
The pair – whose outings included dinner at Chateau Marmont and an animal-filled birthday bash
at a Hollywood talent agent's home – seemed like a good match, according to a source who saw them together this month.
"They almost acted like they've been a couple for a long time," the observer told PEOPLE. "It definitely didn't seem like a new relationship."
Perry was recently divorced
from Russell Brand, and dated
Florence + the Machine guitarist Robert Ackroyd earlier this year.
