Beyonce Knowles will voice Queen Tara in animated movie Epic.

The "Halo" hitmaker will join a star studded cast including Colin Farrell as Ronin, Josh Hutcherson as Nod, Amanda Seyfried as Mary Katherine, Johnny Knoxville as Mandrake, rapper Pitbull as Bufo and Steven Tyler as Nim Galuu in the new movie from the makers of Ice Age and Rio.

Epic tells the story of a teenage girl who finds herself magically transported into a secret universe, where she must band together with a rag-tag team of fun and whimsical characters to save that world, which in turn rescues the real world from destruction.

This is the first film Beyonce has signed up to since giving birth to her daughter Blue Ivy in January.

Epic will be released May 24, 2013.
