WATCH: Lady Gaga Gets Violent In Film Debut “Machete Kills”

Leave it to Mother Monster to rack up a body count in her film debut. In the trailer for Machete Kills, which just leaked online, we catch a brief glimpse of  Lady Gaga as La Chameleón flirtatiously waving to an oncoming truck in the desert roads of Mexico—cue the “Alejandro” track.

Gaga announced she was cast in director Robert Rodriguez’ ultra-violent film last summer after meeting its star Danny Trejo at the Shamrock Social Club tattoo parlor in Los Angeles, according to the New York Post.

There are many big name male celebs (besides Trejo, it co-stars Charlie Sheen, Mel Gibson and Antonio Banderas) in the thriller, but, come on, this is all about its femme fatale cast. Zoe Saldana, Amber Heard, Sofía Vergara, Michelle Rodriguez, Jessica Alba and Vanessa Hudgens are among the other femme fatales who will likely indulge in scantily-clad knife fights and meet bloody, violent endings when Machete Kills opens in theaters September 13.
