See Lady Gaga In First Machete Kills Trailer
Pop megastar gets blink-and-you'll-miss-it spot in action-packed movie trailer...
Introduced by director Charlie Sheen playing the US president - although he is billed as "Carlos Estevez" for the Spanish-speaking market.
The movie is the follow-up to Rodriguez' Machete, which was born from a spoof trailer in the director's Grindhouse project.
A UK release date is yet to be confirmed, but the movie opens in September in the US.
