1. She emerged as the pouty, raven-haired member of 1980s movie phenomenon dubbed "The Brat Pack."

• For improbably outlasting Molly Ringwald, Ally Sheedy, and Mare Winningham -- not to mention all the boys -- to become the Pack's biggest star: +3

2. After such hits as Indecent Proposal, A Few Good Men, and Ghost, she spent a period of the 1990s as Hollywood's most bankable female star.

• For selflessly carrying such box-office dead weight as Robert Redford, Tom Cruise, and Jack Nicholson on her well-aerobicized shoulders: +3

3. Her career suffered, however, after a series of roundly criticized, high-profile vanity projects flopped.

• For barely -- barely -- escaping the fate of starring in the decade's most unintentionally laughable film, only by the hairs on Showgirls's chinny-chin-chin: -1

4. She disappeared into a self-imposed semi-retirement to raise her daughters, before reemerging in a massive publicity campaign built around a role in Charlie's Angels: Full Throttle.

• For actually doing that thing celebrities always say they're going to do but don't: +2
• For probably not having much choice at the time: -2
• For her subsequent spectacular career rebirth...: +1
• ...that wasn't: -2

5. By marrying longtime(ish) boyfriend Ashton Kutcher, she not only solidifies herself as the ongoing poster woman for May-December romances, but proves an entire nation of cynical observers wrong.

• For either proving an entire nation of cynical observers wrong or participating in the single most dedicated, hardcore, and ludicrously over-the-top publicity stunt in recent memory. Either way: +1

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.

1. A former model, he landed one of his very first auditions, grabbing the role of the lovably hare-brained Kelso on That '70s Show.

• Dude, that show went into syndication. All those cats are sick rich: +3

2. Unlike several of his co- (Masterson) stars (Valderrama), Kutcher built on his niche fame and MTV-friendly good looks, parlaying them into the only vaguely obnoxious and intermittently hilarious celebrity prank show Punk'd.

• Come on, you know you watched it. Laughed a few times too: +3

3. He's also built a respectable movie résumé, with some solid if non-blockbuster hits:

• For such films as Dude, Where's My Car, Just Married, Cheaper by the Dozen, Guess Who...: +1
• ...and The Butterfly Effect, My Boss's Daughter, A Lot Like Love...: -1

4. He's also proven to be a youth-culture style icon, helping to popularize, for example, the ironic trucker hat.

• Dad-blammed, rumpin' frumpin' ironic trucker hats: -1

5. He cemented his ascent as a young A-lister with a tabloid-friendly relationship with Demi Moore.

• For cannily turning a Chachi-esque sitcom sidekick role into a place as one of the few bankable(ish) male stars under thirty: +2

Admit it: you were shocked. Not only that they lasted, but that they got married. Married! To each other! Ashton Kutcher is the best thing to happen to Demi Moore's career since she posed pregnant on the cover of Vanity Fair. (Never let it be said that the lady doesn't know how to put a youngling and a magazine cover together for maximum effect.) Hey, we're not saying publicity considerations didn't play some small part in the engagement, but come on: let the newlyweds have their day. Or rather, let them have their six months, at which point Ashton will probably be grabbing the dictionary and looking up the definition of "annulment."
