Katy Perry and John Mayer are making music together..at least in the studio

John Mayer and Katy Perry have been on and off for over a year now and they are pretty quiet about their relationship status but they are definitely making music together in the studio at least.

According to Rolling Stone, Perry sings a duet with Mayer on a "country-tinged mid-tempo track" called "Who You Love," while Frank Ocean appears on the song "Wildlife."

So Mayer did dedicate his song "A Face to Call Home" to Perry at Milwaukee's Summerfest last month, adding that she'd been "so patient" while he struggled with vocal impairments.

Below, check out the first single from Mayer's new album Paradise Valley, "Paper Doll." It features Joanna Rohrbeck, the Prancercise guru. Two questions:

 What do you think of the song?
  And do you think Katy and John will end up together and make smushy babies?

Katy sets her hair on fire to promote her new album

Katy Perry is saying goodbye to her "California Gurls" persona by burning her trademark blue wig.

In a new video clip promoting her upcoming single "Roar," the 28-year-old singer is going dark and making a statement about her new music. We're guessing she wants us to take her more serious? Like, she's moving up the grid from pop musiv to adult/easy listening like her man John Mayer.

The clip starts out with Perry opening a lighter and holding the flame in front of her face while standing in a pitch-black room. Perry, wearing red lipstick, a black collar choker and a striped ensemble, then lifts up her blue wig (made famous by her "California Gurls" music video) and lights it on fire.

Perry stares into the camera looking possessed like she's doing a voodoo ritual  holding her fiery hairpiece for several seconds before "#Roar Aug. 12" flashes across the screen.

"Roar" will be Perry's first single off her upcoming album Prism. Perry announced the title of her album earlier this week with a giant gold truck that was spotted driving around L.A. The gold Prism truck is currently driving around the country.

To mark the occasion, Perry tweeted, "WE DON'T NEED NO WATER LET THE BABY BLUE BURN," along with a link to her wig-burning video.

After all the hype, this album better be good!
