Lady Gaga Debuts New Song in 'Machete Kills' Trailer

Singer plays 'The Chameleon' in upcoming film

By

Lady Gaga scored her first movie role in Machete Kills, and now the singer has loaned a new song to the film's trailer. The track, "Aura," gives the clip with a slithery Western feel as Machete (Danny Trejo) unloads a serving of ass-kicking on the orders of the President (Charlie Sheen). Gaga herself also pops up to give a glimpse of her character's skills with a gun; she is one of several actors to play the character "the Chameleon" in the film.
