When you think of the word “badass,” Lady Gaga doesn’t exactly spring to mind. But that could all change as Mother Monster is set to make her acting debut in Robert Rodriguez‘s upcoming action flick Machete Kills!

Announcing the surprising news on Twitter this morning, the director wrote:

“I just finished working with @LadyGaga on @MacheteKills , she kicked SO MUCH ASS! Holy Smokes. Blown away!”

The “Born This Way” hitmaker will be playing a character named La Chameleón in the sequel to Machete, opposite Danny Trejo, Jessica Alba, Michelle Rodriguez, Vanessa Hudgens, Zoe Saldana, Sofia Vergara, Amber Heard, Demian Bichir, Mel Gibson and Charlie Sheen.

Sharing her excitement, Gaga tweeted:

Yes its true, I will be making my debut as an actress ln the amazing MACHETE KILLS BY @RODRIGUEZ IM SO EXCITED!!! AH! Filming was insane.

In the film, Machete (Trejo) is recruited by the U.S. government to track down an arms dealer (Gibson) through Mexico who plans to launch a deadly missile.
