Don't say we didn't warn you that we were in the mood for year-end roundups. Here are ten celebrity breakups from 2007 guaranteed to make you feel like a more evolved person...

1. Kate Moss & Pete Doherty
It wasn't the five-year age gap and it wasn't all the boozing or the coke-whoring or the failed stints in rehab either. No, the reason Kate finally kicked Pete to the curb with his belongings in a trash bag? He slept with a younger model. Vanity, thy name is supermodel.

2. Rachel McAdams & Ryan Gosling
"The only thing I remember is we both went down swingin' and we called it a draw," Ryan said in GQ magazine's November issue. The general public was so disappointed in the split--who didn't swoon at that kiss?--that apparently strangers still accost Ryan in the street and ask him to fix things.

3. Justin Timberlake & Cameron Diaz
Thank you, Cameron, for making us all feel better about the times we've drunkenly accosted an ex and asked him what the hell he thinks he's doing with that slut.

4. Kate Hudson & Owen Wilson
From Butterscotch Stallion to Suicide Blonde, it was a tough year for poor Owen.

5. Denise Richards & Charlie Sheen
The split may have officially started back in 2005, but 2007 was when things got truly messy: she told courts how he emailed photos of his erect penis to over 30 women on sex websites, and he called her "a sad, jobless pig" and said "go cry cry to your bald mom" via email (her mom subsequently lost her battle with cancer).

6. Heath Ledger & Michelle Williams
Okay, so it wasn't exactly Charlie Sheen-messy, but in our sordid imaginations this breakup involved lots of kinky sex between Heath and Jake.

7. Drew Barrymore & Fabrizio Moretti
Actually, we're mostly just shocked that they lasted as long as five years together. Come on, Drew...the drummer?

8. P.Diddy & Kim Porter
We're so bored of Diddy we can hardly be bothered to mention this one, but after all their on-again-off-again history, we guess they deserve a place in the list.

9. Liza Minneli & David Gest
The breakup that seemed like it would never end, these two finally signed divorce papers in 2007. Who could forget David's allegations that Liza infected him with herpes and then beat him up?

10. Helio Castroneves & Aliette Vazquez
The racecar driver dumped his fiance just one day after winning Dancing with the Stars, amidst much speculation about the chemistry between him and his dance partner. (Are we just jealous hags, or would you have to be toad-licking crazy to let your man participate in this show?!)
