Christian Slater's divorce from estranged wife Ryan Haddon has been finalized, according to legal documents.

Previously, Slater was seeking joint custody of their 5-year-old daughter Eliana and 7-year-old son Jaden, but it's unclear how that issue was resolved.

Slater, 37, and Haddon, 35, a TV producer, married in 2000 and separated in January 2005.

After nearly a week of clubbing, partying and shopping in LA with new BFF, Paris Hilton, Us has learned exclusively that Britney Spears has abruptly pulled out of co-hosting with the heiress on the Fox Billboard Music Awards, scheduled to air live on December 4.

"She pulled out," confirms a source with Fox. "She didn't give a reason."

The source tells Us that Hilton is still a possible host despite losing Spears as a sidekick. Other sources confirm that as recent as this morning, agents for both Hilton and Spears were hashing out the final terms of the contract, but at 5pm today, Spears had backed out of negotiations.

"We really don't know the reason. But we're disappointed she backed out." says a Fox source.

The source says the show may go on with Hilton as solo host, or it may feature comedian (and Fox sitcom star) Brad Garrett, given he's at the top of the show producer's wish list.

At press time, neither Hilton or Spears' reps were available for comment.

Kirsten Dunst could be pregnant! Star magazine claims that she has a baby bump, back pain, morning sickness and an unnatural interest in the pregnancies of her coworkers:

Kirsten Dunst has been generating rumors that she may be the next actress to be sporting a baby bump on the set of her upcoming film Spiderman 3. She has been spotted wearing baggy clothing, ordering big boxes of sweet chocolaty treats, and overheard complaining of lower back pain and nausea during filming.

Her rep denies that these tell-tale signs are signaling that Kirsten is a mom-to-be, but her interest in co-star Tobey Maguire’s newborn daughter suggests otherwise.

Kirsten has become fascinated by details about the pregnancy of Tobey’s fiancée, Jennifer Meyer, asking how she dealt with morning sickness. When Tobey replied that Jennifer felt awful throughout the entire nine months, Kirsten just groaned, “Oh great!"

If Kirsten is anticipating her own nine-month struggle, fans wonder, who’s the daddy? Kirsten dated her Marie Antoinette costar Jason Schwartzman briefly and recently announced her relationship with Orlando Bloom.

But Kirsten was seen with former-love Jake Gyllenhaal this month too. They weren’t cuddling or all over each other, so maybe the old flames simply reunited to share some new baby news!
