Taylor Swift is the girl of many young men's dreams -- no secret there! Now, she's focused on being the girl of Zac Efron's dreams, voicing the part of Audrey in the animated adaptation of the children's classic, 'Dr. Seuss' the Lorax.'

Zac lends his voice to the character Ted, an idealistic young boy who is smitten with Taylor's character and strives to find a way to win her affection. In his search he discovers the story of Lorax, a grumpy yet lovable person fighting to save the world.

The 3D film is a project of Universal and Illumination Entertainment. Danny DeVito (who voices the title character), Ed Helms (as Once-ler), and Betty White (as Ted's grandmother, Netty) also star in the film that reunites many players from the 2009 movie 'Despicable Me,' Illumination's first movie. Audrey Geisel, Seuss' widow, serves as executive producer.

Set for a March 2, 2012 release, 'The Lorax' is Taylor's second big film. Her first was last year's 'Valentine's Day.'

The four-time ACM award nominee is currently in Europe for her Speak Now tour. She plays in France tonight (March 17), followed by shows in Spain, the United Kingdom and Ireland. Keep track of her world travels here.
