Los Angeles: Pop star Lady Gaga has reunited with her 'Poker Face' producer RedOne in the studio for her new album.
The 28-year-old singer revealed she's working with the producer again when she shared on Instagram a photo of them hanging out in the studio, reported Ace Showbiz.
RedOne has co-written and produced some of Gaga's biggest hits in her career, including 'Poker Face', 'Love Game' and 'Just Dance' from her 2008 debut set The Fame.
The duo also worked together for some tracks on the album's follow-up, 2011's Born This Way.
The Swedish musician co-wrote only one song called 'Gypsy' for Gaga's latest album, 2013's ARTPOP, which has been considered as a flop as it fails to match the sales of its predecessor. Gaga confirmed her new album last month.
