When Stars Split: The Methodology

When you're a fully-fledged celebrity, doing nothing in your spare time but appearing on talk shows and soaking up free champagne at movie premieres, it stands to reason that the only people you ever meet are other celebrities. Hence: The All-Celebrity Hook-up, which very often makes a successful transition to The All-Celebrity Relationship.

But the overwhelming majority of All-Celebrity Relationships carry the seeds of their own destruction: each mate is forever being exposed to other likely prospects, the public gets bored seeing the same two faces together all the time, and let's face it: breakups get much more press than happy marriages do.

When Stars Split is a service of Fametracker for celebrities ending their relationships with other celebrities. Fametracker will use this space to determine who in recently busted-up celeb/celeb pairings leaves the partnership with the advantage, and who leaves used-up and broken-down.

1. He was one-fifth of 'N Sync.

• Remember boy bands? Great, now we feel old.: -3

• Well, that makes one movie that's actually come out in theatres: -2

4. He's twice hosted Saturday Night Live.

• Robin Gibb!: +1
• Omeletville!: +2
• DICK IN A BOX!: +3

5. He's bringing sexy back.

• YEAH he is!: +5

Cameron Diaz, you have made a huge mistake. Sure, when you entered into this relationship, Justin Timberlake was a Lou Pearlman protégé, a Britney Spears castoff, and a white (sometime) rapper. A stint on The Surreal Life seemed likely. But over the past three and a half years, things have changed. The Charlie's Angels sequel tanked. Starring in films opposite the likes of Daniel Day-Lewis, Toni Collette, and Kate Winslet might have seemed like it would give Diaz prestige, but instead it just proved how absurd it is that a lox like Diaz not only styles herself an "actor," but makes an obscenely good living at it. And meanwhile, Justin Timberlake? TURNED AWESOME. God, she must have known when she first saw "Dick In A Box" that she'd be getting a "Dear Shrimp" letter very soon.
