Justin Timberlake Grossed Out by Incestuous Shrek 3 Role  1/13/06

Pop hunk Justin Timberlake was disgusted to find out his Shrek 3 character will be a relative of his girlfriend Cameron Diaz's character Princess Fiona.

The Cry Me a River singer is set to voice the role of Prince Artie - the future King Artur - in forthcoming Shrek 3, which is set for release next year (07).

And instead of playing a love interest to Diaz's Princess Fiona, Timberlake will voice her cousin.

He moans, "I believe our characters in the movie are cousins, so that's disgusting.

"I mean, I'm from Tennessee, so I heard it does happen where I'm from. But you know, I don't think it's such a good thing universally.

"It's a kid's movie. I don't think cousins should be doing that kind of thing."
