Katy Perry told Vogue that John Mayer broke her heart, but then they were photographed together, and he dedicated a song to her, so you had to assume they were at least partially back together. Today, some pretty solid evidence: Perry will be featured on Mayer’s upcoming album. The song is called “Who You Love,” and we are going to assume that the answer is “each other,” so: Way to work it out, kids. P.S.: Frank Ocean is on the album, too.
