1. She is a multi-platinum-selling recording artist.

• For capitalizing on the tendency of affluent white parents to give their pre-teens ever-larger weekly allowances: +4

2. She dated Justin Timberlake for several years.

• If she had to date a member of 'N Sync, at least it wasn't the gay one: +1
• Not that her whole "I'm still a virgin" routine actually fooled anyone: -2

3. She famously kissed Madonna during a performance at the MTV Video Music Awards.

• So did Christina Aguilera, but no one remembers that part: +2
• And that was back when Madonna was still somewhat cool and subversive, and not just the twenty-first century's Sean Young: +1

4. She appeared in an extensive ad campaign promoting Pepsi.

• We had one of those plastic collector cups from the movie theatre for...actually, it may still be out front in a bag of ice melter: +2
• In doing so, she apparently gave Bob Dole a boner: -3

5. She spent an hour earlier this summer defending her life to America, via Today's Matt Lauer.

• She should have considered doing so without the gum, in an outfit that covered more of her ass, and having showered: -2
• However, we saw her on Letterman Monday night, and she has really bounced back: +3

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 started his career as a backup dancer for musical acts, including his future wife.

• And Michael Jackson: -3
• And Target!: +2

2. He fathered two children with his former girlfriend, Shar Jackson, and two with Spears.

• So his junk works: +1
• Four kids, two moms, and all before his thirtieth birthday -- every move a right one: -2
• Plus that's a lot of his DNA just walking around, out in the world, able to vote someday: -3

3. He made his professional acting début in the October 12 episode of C.S.I.

• He was quite convincing as a petty thug: +2
• Unfortunately, the episode did not end with his gruesome, slow-motion death: -3

4. His first solo album was released last week.

• Remember? You camped out in front of the record store for it! Not.: -2

5. Several dates in support of the album have been cancelled due to sluggish ticket sales.

• Even though tickets were priced under $20 -- less than he probably spends, on any given day, to treat his crabs: -3

No one was surprised to hear that Britney Spears was divorcing Kevin Federline -- not the press, not her mom, not Justin Timberlake, not Jason Allen Alexander, and probably not even Federline himself. Because, you know, we all had our fun at Spears's expense when she broke up with Timberlake, and lost her Pepsi deal, and had her record tank, and starred in the terrible Crossroads, and lord knows she didn't always show herself to her best advantage espousing Republican Christian values and wearing her kabbalah bracelet and walking around Los Angeles shoeless and braless and just generally looking a mess, but even so...she's still a star, of sorts, and he's KEVIN FEDERLINE. Because Spears seems like a sweet (if painfully dumb) girl, we hope the announcement that she's getting rid of Federline is just the first step in her handlers' multi-step comeback plan, and in his descent from the WWE (yeah, that's right) to The Surreal Life to a shallow pauper's grave.
