Madonna And Mike Tyson Might Bring Us The Strangest Collab Of 2015

Plus, Chance the Rapper.

Late last year, Madonna released six new songs, including "Bitch I'm Madonna," featuring Nicki Minaj. And as exciting as that was, it was a pretty tame collab compared to what else she has in store on her upcoming album.

The track list for Rebel Heart, due out in March, hit iTunes on Monday, and brought us a handful of surprises. One, though, seemed particularly peculiar: "Iconic," which will feature Chance the Rapper and Mike Tyson.

Yup, Mike Tyson.

Madge isn't the first to feature the former boxing champ on wax, as Canibus grabbed some vocals from Tyson on "Second Round K.O.," from his 1998 album Can-I-Bus.

Tyson isn't the only heavyweight on the project, though. The Queen of Pop also got Nas for her thirteenth solo album, which drops March 10.
