Lady Gaga teases new music with RedOne

Lady Gaga has begun recording new music with RedOne! In a new photo posted on Gaga's Instagram, Mother Monster is shown in the studio with the long-time collaborator, who helped her create some of her biggest hits, including "Just Dance," "Poker Face," and "Bad Romance," as well as fan favorites "Hair," "Scheiße," and "Gypsy." The caption reads, "We wear our sunglasses at night."

Gaga went on to share two more posts from their studio session: a picture of the audio waves and a silent video of RedOne playing the electric guitar.

Lady Gaga first announced that she was working on new songs with RedOne back in January.

"With Gaga, I'm fully committed until we're done – we're just going to work on writing songs until we get hopefully the best album of the decade," RedOne said earlier this year. "The new material feels great. And that's what it is like with me and her – when we both feel great, it's incredible. A lot of it is to do with trust, no ego, just love for the music. And when it's fun and respectful, putting the egos aside, it's magic."
