Lady Gaga brandishes a machine gun in first 'Machete Kills' trailer - watch
Singer makes her acting debut in Robert Rodriguez's sequel to his 2010 cult hit 'Machete'
Lady Gaga makes her acting debut in the action sequel, playing a character called La Chameleón. The trailer features two quick glimpses of the singer, who is seen hitchhiking and then brandishing a machine gun.
Danny Trejo returns as deadly assassin Machete Cortez and the sequel sees him recruited by the President of the United States to track down a crazy and dangerous billionaire arms dealer played by Mel Gibson.
Meanwhile, Michelle Rodriguez and Jessica Alba have also reprised their roles from the original Machete film, which came out in 2010 and quickly became a cult favourite.
New additions to the cast include Antonio Banderas, Sofia Vergara, Vanessa Hudgens and Charlie Sheen - who is credited in the trailer as "Carlos Estevez", his birth name. Machete Kills opens in US cinemas this September, but the UK release date has yet to be confirmed.
