K-Pez herself later tweeted a link to Vanity Fair's picture exclusive of the artwork shoot, which shows the loved-up couple posing for a number of sultry black-and-white shots by photographer, Mario Sorrentil. 

Who You Love is the third single to be taken from Mayer's new album Paradise Valley, with the 36-year old previously saying of the tune: "I wouldn’t have brought her a song if I didn’t think it was good and great and she wouldn’t have said she would do it if she didn’t think it was going to be great.So it was a completely artistic transaction.”

As for the experience of collaborating with his partner, Mayer went on to explain: “I think the power of the song protected me, certainly, I don’t know about her, from it being a little too cute.”

Katy also recently described their duet as "incredible", adding: "I'm so proud of it because people hear it, and they hear a different side of me."
