It’s cameo time. Lady Gaga, who revealed acting aspirations last winter, will appear in Robert Rodriguez’s forthcoming  ‘Machete Kills.’ You know the Double R. He directed ‘Sin City,’ and ‘Machete Kills’ is the sequel to his 2010 action exploitation flick ‘Machete’ starring Danny Trejo. Rodriguez shared the news on Twitter, along with an amazing, frameworthy poster of the Mother Monster.

Here’s what we know: Gaga is playing La Chameleon, and she looks like Marilyn Monroe if she was hired as a surrogate for Mae West and produced Gwen Stefani. She’s all kinds of va-va-va-voom Old Hollywood glam, with a white fur stole (is that a wolf?), painted lips, a statement bauble, a bustier, garters, massive waves and a smoking gun. Literally. She’s holding a just-fired weapon. She boasts all the things a gal needs.

Be careful where ya point that thing, Gaga.

Rodriguez was beyond stoked to add Gaga to his cast. His tweet read as follows:” I just finished working with @LadyGaga on @MacheteKills , she kicked SO MUCH ASS! Holy Smokes. Blown away!”

There are no further deets about La Chameleon, other than she likes to show some leg and brandishes a pistol. Perhaps the role will be little more than a blink-and-you’ll-miss-her cameo. Or maybe Gaga will get more than a few moments of screen time. If we had to judge based on the poster, we’d think she’s going to have a bit of small but crucial role. Maybe a speaking part? A villainess role? We’re becoming fan fiction authors.

Gaga isn’t only the unconventional and unusual casting choice. Charlie Sheen also grabbed a role. Winning! So did Mel Gibson. Bring on the on-set rant!

What do you think of the poster and La Chameleon, PopCrushers?
