Men In Black 3 actress Lady Gaga has announced she'll star in Robert Rodriguez' new film Machete Kills.

The 'Marry The Night' hitmaker will play La Chameleon in the film, which also stars Charlie Sheen and Jessica Alba.

But don't take our word for it

"Yes its true, I will be making my debut as an actress in the amazing MACHETE KILLS by @RODRIGUEZ IM SO EXCITED!!!" she said upon the Twitter. "AH! Filming was insane."

Rodriguez, meanwhile, had this to say about it all: "She kicked SO MUCH ASS! Holy Smokes. Blown away!"

The film doesn't have a release date as yet, or at least not that we know of.
