Hear Lady Gaga's Aura on new Machete Kills Trailer
Pop star's character forms focus of latest promo for action flck...
And the singer also provides the soundtrack for the promo, which is set to a new electro-style track called Aura from her forthcoming album ARTPOP.
Her character, Lady Chameleon features heavily in the fast-paced trailer - at one point aiming a gun at somebody's head and asking: "Straight up, or with some flair?"
Michelle Rodriguez, Danny Trejo, Mel Gibson, Charlie Sheen, Sofia Vergara and Amber Heard are also seen in the trailer - which ends with an advert for Gaga's album.
Machete Kills arrives in cinemas this Friday.
