It's Mustardney on the beat, bitch.

More than a year after first confirming the collaboration, DJ Mustard is yet again teasing his track with The Legendary Miss Britney Spears — and he's finally unveiled the song title: "Mood Ring."

"@britneyspears mood ring produced by @DJmustard coming soon 😊 ...." the producer tweeted late this evening (August 9), which follows a string of new Brit Brit song confirmations, including Glory tracks "Clumsy" (which arrives tomorrow evening as an instant grat!) and album opener "Invitation."

"We got something harder than hard," he first revealed during an interview at last year's Wireless Festival.

As confirmed by an ASCAP listing, "Mood Ring" was co-written by Jon Asher and songwriter Melanie Fontana and produced by DJ Mustard.

“It’s cool, it’s really different. I think this is probably the most hip-hop album — not most, there are like two or three songs that go in the direction of more urban that I’ve wanted to do for a long time now, and I just haven’t really done that," Britney said of the recording sessions for her new record in an interview with Ryan Seacrest.
