"She needs a new challenge and has set herself a target of winning an Oscar in five years," a source said.
The singer had a fleeting cameo appearance in Men In Black 3 last year and now wants to land a leading role. The pop star is set to make her big debut in Machete Kills, a film directed by Quentin Tarantino's regular collaborator Robert Rodriguez.
Eccentric Gaga plays a sexy gun-wielding character named La Chameleon in the sequel to the 2010 movie Machete, starring opposite Mel Gibson, Jessica Alba and Amber Heard.
"Yes its true, I will be making my debut as an actress in the amazing Machete Kills by Rodriguez. I am so excited. Filming was insane," she recently tweeted.
