Lady Gaga will make her acting debut in 'Machete Kills'.

The 26-year-old actress took to her twitter account to confirm she has joined the cast of Robert Rodriguez's action movie - a follow up to 2010's 'Machete' - as La Chameleon, and she can't wait to see herself in the motion picture.

No further details of Gaga's alter-ego have been revealed, but Rodriguez took to his twitter account to unveil the 'Poker Face' singer's character poster, which shows the singer holding a dead white wolf and a smoking gun while dressed in suspenders.

The director admitted Gaga "kicked so much ass" while filming her role in 'Machete Kills' and insists he was "blown away" by her performance.
