When Stars Mate: 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.

The problem is, if you're a celebrity, the odds are that your worth, and that of your mate's, will never be evenly matched. Therefore, when you meet and fall in love with another celebrity, either your worth, or that of your mate, will necessarily go down.

When Stars Mate is a service of Fametracker for celebrities dating, or married to, other celebrities. Fametracker will use this space to determine who in current celeb/celeb pairings has gained by the relationship, who has lost, and how the balance of power could be altered.

2. He has gone on to partner with Damon on many projects.

• For continuing to work with his friend despite those who speculate that they are "partners" in more ways than one: +2
• And for not throwing a hissy in response to public speculation that he could be gay, Tom Cruise: +3

3. His last four movies were Surviving Christmas, Jersey Girl, Paycheck, Gigli.

• For transforming from a perfectly serviceable young movie star into a one-man flop factory: -4

4. His past fiancées include Gwyneth Paltrow and Jennifer Lopez.

• Buddy's got a bitchface jones, it would seem: -2

5. He is a consistently engaging guest on talk shows and Saturday Night Live.

• For having such a healthy sense of humour about himself and his many foibles that we just cannot manage to hate him, no matter how hard we try: +3

We admit it: Jennifer Garner represents a great leap forward from the last Jennifer to whom Ben Affleck was engaged; she may not be the brightest bulb in the chandelier, but Garner seems like a nice enough girl. She is not the problem here. Granted, their respective mate ratings make them pretty evenly matched, on paper. But what the numbers alone don't tell you is that she's a 5 and rising, whereas he was rated a 7 just three years ago; he's a 3 and falling. Jen, we liked you much better with Vartan. Don't let Wigfleck drag you down to his level.
