Katy Perry & John Mayer: 'Who You Love' Video

Katy Perry and John Mayer took to Good Morning America on Tuesday to premiere their new music video, Who You Love.

The two stars, who have been dating for more than a year, collaborated on the song for Mayer's latest album. The ballad is an ode to finding love with someone, even if it is unexpected. The couple explained to the GMA anchors how they translated that concept into video form.

"We set the casting call up for real couples. It's just so authentic - they were having a great time," Mayer, 36, said. "There's nothing scripted in that video except putting the bull in the middle of the desert."

The video also featured the couples riding a mechanical bull. Perry said that was the essence of most relationships.

"Relationships are kind of like riding a bull - you hold on for dear life. Sometimes you get a little a little buck here and there, but you get back on," Perry said.

Watch the clip below.

Perry also took to Twitter to promote the song and video.
