R&B superstar Beyonce, rocker Steven Tyler and rapper Pitbull are getting animated for a new out-of-this-world 3D film project by Ice Age director Chris Wedge.

The three musicians have been cast to voice characters in Epic, joining actors Colin Farrell, Amanda Seyfried, Josh Hutcherson and comedian Aziz Ansari.

The movie follows the fortunes of a teenage girl who has to save the earth after she is transported into another universe.

Epic will be Beyonce's first new film job since becoming a mother to daughter Blue Ivy in January. She is also due to begin production on Clint Eastwood's upcoming remake of A Star Is Born later this year. Work on the updated classic had to be delayed in 2011 when the Dreamgirls star got pregnant.
