John Mayer, Katy Perry and a mechanical bull star in the new music video for "Who You Love, the third single off of the singer-songwriter's Paradise Valley album.
Premiering today on Good Morning America, the video features Mayer, Perry and other couples riding a mechanical bull before shooting off confetti cannons.
"We set a casting call up for real couples. It's just so authentic ... they were having a great time," Mayer, 36, says of the collaboration with his girlfriend.
"There's nothing scripted except putting the bull in the middle of the desert."
Katy adds, "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."
She was up for the collaboration ... both personally and professionally.
"[John]'s just a fantastic partner," she added. "I've been a fan of his for such a long time. He's got a brilliant, brilliant mind. It's a rad, mature relationship."
