UPDATE (11/20): The full version of Iggy Azalea's new Ellie Goulding collaboration "Heavy Crown" has surfaced. Word to the wise: If you're thinking about messing with these new pop princesses…well, think again. On the grinding, hip hop/pop track, Iggy and Ellie know they're on top and aren't planning on moving from their spot anytime soon.

Iggy laughs in the non-believers' faces with an unforgettable verse: "For everyone who said I'd never make it / Oh Lord, weren't you mistaken? / I got a dinner date with greatness / Iggy, Iggy, I ain't never been nothin' to play with."

Meanwhile, Ellie chants on the chorus, "This heavy crown / You can't always please the crowd, but I am still not bowing down  / This heavy crown / It comes and goes around / And when it's still time, I'll pass it proud / But bitch, I got it now." Listen below.

Original Story: Iggy Azalea's already shown that she's into the action movie aesthetic with the video for her recent collaboration with Rita Ora, "Black Widow." Now, it looks like she's going back to the kung fu drawing board—or at least she's partially inspired by it, as her new duet with Ellie Goulding is soundtracking the first official trailer for hard-fighting flick Kingsman: The Secret Service.

The beat kicks in around 1:15 of the trailer, with Iggy's verse ("I've got a dinner date with greatness") making a grand entrance following ample judo chops, bar brawls and Samuel L. Jackson screaming at the 1:50 mark. Ellie's smooth vocal line comes in a bit later and is juxtaposed by, well, more carnage and cries from Samuel L. Jackson. It's fast. It's intense. It's rad. And it's a totally intriguing sneak peek of what's sure to be a scintillating duet.

Iggy's been keeping busy lately: her Ellie duet is just the latest in a number of spotlit collaborations, from Rita to J. Lo to J. Hud to Ariana to Charli. She may be the most popular rapper in the game at the moment—definitely with the pop stars, anyway—but it looks like she's going to be the talk of Hollywood, too.
