It's Miley and Madonna!

Just days after Madonna released the cover art -- and six new songs! -- from her upcoming new album, 'Rebel Heart,' we've learned that Miley Cyrus has actually co-written one of the Material Girl's newest tracks.

According to a Miley Cyrus fan account, the 'Wrecking Ball' singer co-wrote 'Wash All Over Me.' You can check out the tweet below, which appears to be a screen grab of the writing credits:

While the collab doesn't come as too much of a surprise -- especially considering Madonna seemed to tease it a while back and the two have already performed together on Miley's 'Unplugged' special earlier this year -- it still makes us insanely excited to hear it.

In addition to Miley, Madonna's thirteenth album is filled with even more surprising pop influences, including a collab with Nicki Minaj -- as well as production by Ryan Tedder, Avicii and more.
