EARLIER // JULY 11:
Selena Gomez introduces her "best friend" Charlie Puth on stage to sing "We Don't Talk Anymore."
Fans attending Gomez's Revival Tour in Anaheim, CA on Sunday (July 11) were treated to a special performance of the pop star's collaboration with the Nine Track Mind crooner.
Puth, who opened up the show following Gomez's staple tour opener, Bea Miller, sat at the piano to play the tune while Gomez rocked a leggy black dress to sing on stage. It marks the first time the pair performed the song together since January.

Last month, Puth confirmed a music video for the song is being shot in NYC, but is taking so long to premiere because he wants it to be "perfect."
