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.

When they first appeared together, each buoyed the other ­- she gave him a shot of sexy glamour, while he gave her a shot of humane charm. Since then, Grant has managed to maintain his appeal despite his storied offscreen exploits; in fact, he's established himself -- in films like Notting Hill, Mickey Blue Eyes, and, now, About A Boy, as a successful Hollywood brand: the Lovably Hapless Rake. Hurley, however, has careened into career hell, undercutting early successes like Austin Powers with duds like EdTV. Furthermore, she's gone from Hollywood's sultry foreign siren to Hollywood's embarrassing overseas cousin who gets too drunk at family gatherings and threatens to ignite the curtains with the fumes of her breath. And then gets knocked up by an old boyfriend who won't return her calls. It's strange to think that one of these people got caught having sex with a hooker in a car, and that's the one whose career is going well.
