John Mayer and Katy Perry's 'Who You Love' Hits Web (Audio)
Hear the real-life lovers perform a ballad from Mayer's upcoming "Paradise Valley" album.
"Roar" isn't Katy Perry's only new song.
The singer is featured on on-again boyfriend John Mayer's "Who You Love," a track from his upcoming Paradise Valley album. The set is due Aug. 20, but the duet has made its way online.
The soft ballad, punctuated by Mayer's lead guitar licks, finds the pair trading verses and sharing the track's titular chorus: "Love who you love, who you love."
"You're the one I love," Perry sings to close the track before bursting into a giggle.
Perry's own Prism is due Oct. 22. "Roar," the lead single, is out now.
