The 29-year-old singer has posted a number of pictures of her session in the studio, and although guitars are involved (gasp) we're safe in the knowledge that it's the 'Bad Romance' producer who's working with them.
"We wear our sunglasses at night," Lady Gaga posted underneath a picture of herself and RedOne at the keyboard, along with the hashtag #LG5.
Thinking about it, 'We Wear Our Sunglasses at Night' sounds like a very Lady Gaga song title.
Anyway, that picture was swiftly followed by a close-up video of an electric guitar, along with some sound waves that could potentially be giving us the first glimpse of next year's biggest hit.
Lady Gaga first got into the studio with RedOne for her fifth album back in January, and has since been working with the likes of Nile Rodgers, Sir Paul McCartney and Diane Warren.
RedOne has previously produced some of Gaga's biggest hits, including 'Poker Face', 'Just Dance', 'Bad Romance' and 'Judas'.
The star's new album will serve as the follow-up to 2013's ARTPOP, as well as 2014 jazz album Cheek to Cheek with Tony Bennett.
