Despite reports that the pop stars are hooking up, a source tells PEOPLE: “They have not been anything other than friends.”
Gomez, 23, teamed up with the “Marvin Gaye” crooner, 24, to record ”We Don’t Talk Anymore,” a sexy duet on his debut album Nine Track Mind.
“I’m good friends with her now, and we talked about wanting to collaborate, and I was finishing the song, and I was like, ‘Wouldn’t it be cool if you sang the second verse?’ And that’s really how it happened. She came over; she recorded it,” Puth told PEOPLE in January. “I didn’t even have a studio set up: she recorded it in my closet, and it really added a lot to the record.”
Puth will join Gomez on her Revival World Tour this summer.
