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.
