This is bound to soar to the top of the charts!

Gwen Stefani and Eminem teamed up to record their "Kings Never Die" single for the Southpaw soundtrack, and we don't know why they haven't collaborated before! We love this jam!

"I complain about the game, I shout and I pout, it's a love-hate / But I found out that I can move a mountain of doubt / Even when you b*tches are counting me out, and I appear to be down for the count," Slim Shady raps in some of the lyrics.

Southpaw is a boxing drama starring Jake Gyllenhaal and Amy Adams.

Now we are waiting patiently for the music video!
