Madonna has confirmed that she has collaborated with Alicia Keys on her new album.

The pop icon posted a picture, claiming that Keys had been 'killing it' on her upcoming LP. Madonna has yet to confirm the release date for her 13th studio album.

The singer made the post in support of Keys's #WeAreHere project, named after her new single 'We Are Here', which calls for a more peaceful world for children.

Producer Diplo has posted a similar photo of himself supporting the campaign, while he also posted a picture of him working with Keys in the studio. Diplo recently spoke about working with Madonna on 'Bitch, I'm Madonna', saying the track is 'very cool'.
