Soon to be vamping it up on a movie screen near you: Lady Gaga. Mother Monster has been cast in Robert Rodriguez' "Machete Kills," a film well known for its oddball casting. The singer apparently already put in work on the set, and has her own PETA-friendly poster to boot.

The "Planet Terror" and "Sin City" director announced the news on Twitter Thursday:


Robert Rodriguez
I just finished working with on , she kicked SO MUCH ASS! Holy Smokes. Blown away!

Gaga confirmed her involvement, reiterating that this was her acting debut (super-long music videos notwithstanding):


Lady Gaga

LADY GAGA AS LA CHAMELEON IN MACHETE KILLS DIRECTED BY ROBERT RODRIGUEZ STARRING DANNY TREJO (YES THIS IS REAL)

Gaga plays La Chameleon and joins a cast that includes (deep breath) Amber Heard, Sofia Vergera, Zoe Saldana, Jessica Alba, Danny Trejo (Machete himself), and Alex Vega (who played one of the titular characters in "Spy Kids" and recently Instagrammed a photo of her risque costume).

None of these casting choices, however, are as surprising as Rodriguez' pick for the film's U.S. President: Charlie Sheen. Also rumored to be popping by? Mel Gibson.

The film, which is a follow up to Rodriguez' 2012 B-movie "Machete," has no release date. Trejo's character will reportedly be seen trying to stop an arms dealer from hastening the end of the world. Check out Gaga's poster below.
