Hear Lady Gaga's 'Aura' In Brand-New 'Machete Kills' Trailer

Soon, the ARTPOP track will debut in full with a 'Machete'-themed lyric video.

Lady Gaga isn't just ready to make her big-screen debut in "Machete Kills"; she's ready to give fans new music along with the new trailer. The Mother Monster's new track, "Aura," just made its debut in the brand-new clip for Robert Rodriguez's new movie.

Gaga plays a glamorous, gun-toting bad girl, Lady Chameleon, in the campy flick, out October 11. We see even more Gaga than before in the latest trailer, which premiered Friday (October 4).

The singer played "Aura" live during her iTunes Festival gig last month, ahead of her November 11 album release, ARTPOP. The dance track is full of gangly guitar, a house beat, synths and aggressive vocals.

On the track, she wonders, "Do you want to see the girl that lives behind the aura?" as the action of the flick plays out in the background. Not enough "Aura" for you? Well, a special "Machete Kills" lyric video, featuring the entire song, will premiere on Tuesday, October 8.

"Machete Kills," the sequel to 2010's "Machete," also stars Danny Trejo, Michelle Rodriguez, Sofia Vergara, Amber Heard, Carlos Estevez (a.k.a. Charlie Sheen), Antonio Banderas, Jessica Alba, Alexa Vega, Vanessa Hudgens, Cuba Gooding Jr. and Mel Gibson.

The Rodriguez/Gaga love affair is hardly over. Next up, she will team up with Rodriguez again when she makes a cameo in the upcoming "Sin City: A Dame To Kill For," which will hit theaters on August 22, 2014.
