Rah, rah, ah, ah, ah.

Roma, roma, ma.

Gaga, ooh, la-la

What-what, what-the-fuck?

Lady Gaga wrapped her scenes as La Chameleon today in Robert Rodriguez’s Machete Kills, a sequel to the director’s 2010 grind-house actioner Machete. Rodriguez broke the news today—and revealed the poster seen above—on his Twitter feed.

Rodriguez tweets:

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

Gaga joins a cast that includes Charlie Sheen, Mel Gibson, Sofia Vergara, Zoe Saldana, Amber Heard, twins Elise and Electra Avellan, Demian Bechir, Edward James Olmos and returning players Jessica Alba, Michelle Rodriguez and Danny Trejo as Machete.

Machete Kills follows Machete as he’s recruited by the U.S. government to bring down a billionaire arms dealer (Gibson) plotting global warfare with a high-tech space weapon. The film is currently shooting in Austin, Texas for a 2013 release.
