During the DreamWorks Animation Now presentation at New York City's Lincoln Center yesterday, Justin Timberlake was revealed to be the latest addition to the cast of Shrek 3. The former 'N Sync heartthrob will be voicing King Arthur, to be portrayed in the film as a disinterested teenager named Artie. Gee, wonder who Cameron Diaz's boyfriend had to sleep with to get that gig... and where we can line up to apply for Shrek 4. Meanwhile, British tabloids are reporting that Ozzy and Sharon Osbourne accidentally leaked Diaz and J.T.'s secret plans to get married in France this weekend. There's been no official comment from the would-be bride and groom.
