John Mayer and Katy Perry Back Together / Couple Duet on "Who You Love" / 'Paradise Valley' Release Date August 20 [AUDIO]

John Mayer and Katy Perry are back together and in the studio together. The recently reunited couple just released their first duet "Who You Love".

Off the new track, possibly featured on Mayer's upcoming album Paradise Valley, "It's very humanizing,"

"It's like the real moment, you're catching the real moment there," the Roar singer added.

Speaking of real moments, "Who You Love" ends with an affectionate sound from Perry.

"I think that's just a love giggle," Perry explained to SiriusXM Hits during "The Morning Mash Up" on Monday.

"It's like the ones that Mariah Carey had in 1990 and stuff like that ... Yeah I think I was going for that, I think I was just so happy, I love that song."

Back in July, Perry opened up about her relationship with Mayer claiming she was "still madly in love" with the Paper Doll singer.

"I realized I could lose the person I loved and I had to deal with some things, issues I think a lot of women have. You can be strong in one aspect of your life but submissive in another."

John Mayer is set to release his sixth studio album Paradise Valley August 20.
