Cameron Diaz loves lending her voice to PRINCESS FIONA in the animated Shrek movies - because she never has to think about her image. The blonde beauty has famously battled acne, and has previously admitted her desire for more shapely curves. But voicing the ogre princess allows her to concentrate on her art instead. Diaz, who is currently working on Shrek III, says, "It's great. I don't have to worry about my skin or my figure."
