Madonna has revealed she is collaborating with Natalia Kills for her next album.
The MDNA songstress shared an image on Instagram of her in the studio with the British singer and Martin Kierszenbaum, founder and chairman of Cherrytree Records (Natalia's record label) and a senior executive for Interscope Records, reported Billboard.
"Working the midnight shift with Natalia Kills. 2 girls on a couch... don't it taste like Holy Water? #artforfreedom #rebelheart #revolutionoflove," she wrote.
In the photo, Madonna and Natalia sit in front of two microphones, with Martin - who has also worked with Lady Gaga - in the foreground.
The Vogue star confirmed she had worked with Swedish DJ and producer Avicii, when she posted a photo of her with the Wake Me Up and Hey Brother hitmaker on Instagram.
"The end of a long week with Viking Leader AKA DJ Virgo AKA Avicii! So many great songs! #icantwait #revolution," she wrote in March.
Madonna revealed that plans were "in the works already" for her 13th studio album, although no release date has been announced yet.
Actress-turned-singer Natalia, who previously appeared in Casualty, Coronation Street and Silent Witness, has been focusing on her music since she moved to Los Angeles in 2008. She released her debut Perfectionist in 2011, followed by second record Trouble in 2013.
