Most Enthusiastic Cute Girl Accompanied by Cranky Old Guy: Regis and Kelly went balls out on Live this year, dressing up not only as Posh 'n' Becks, but also as Harry Potter and Hermione. Shockingly, Kelly rocked both costumes. We have to hand it to her: It takes talent to pull off both Stroppy English Pop Star and The World's Most Famous Brainy Girl Wizard in the same hour.









Most Deluded: Rumer Willis seems to be under the impression that she's famous enough to pick a costume that's barely recognizable and largely without pants — as she did this weekend in a showgirl-ish getup and oddly Demi-like wig — and expect us to let it pass. Au contraire, celebuspawn. We just learned your name. Pick a costume we can identify.









Biggest Stretch (Marks): Ellen DeGeneres danced down to her talk-show stage as celebrity womb-tease Jennifer Lopez, complete with long brown wig, garish seventies-style pantsuit, and a pregnancy belly she purposely ignored even as it gradually swelled to the size of a small planet. Seeing Ellen dolled up with girlie tresses was jarring, but the even stranger thing was how hot she looked. We're guessing Portia will want to keep the wig for the home game.









Most Painfully Obvious: Tragic Britney Spears staggered around town as a "pirate" (see above), although the effect was closer to "waitress at a pirate-themed strip club." It's a tad too on-the-nose — she's already pillaged and plundered her own life into smoking ruins, and honestly, she probably already has real scurvy.



Biggest Yawn: As always, Paris Hilton hiked up her skirts and brought out the garter belts, tramping it up with two costumes: Sexy Sailor Girl (see above) and, creepily, Sexy Alice in Wonderland (see below) – who, we must note, is WAY underage and has no business flaunting her, well, business. But then again, Paris isn't herself if she's not giving it away for free.



Strangest Allegorical Choice: Larry Birkhead — the DNA-tested, court-approved father of Anna Nicole Smith's baby — dressed up as a key player in the original (and still the best) paternity scandal: Darth Vader. We assume he's turning a blind eye to Vadar's hobbies of blowing up innocents and sword-fighting with his offspring; otherwise, we look forward to a lot of teenage whining before Larry lops off Dannielynn's hand during an argument about her curfew.







Most Appropriately Trashy: We're not a huge fan of Audrina from The Hills — what's with her terrible eyeliner? — but she gets props for doing the typical Trashy-Sexy thing the smart way: by dressing as an actual Trashy-Sexy Person: Madonna circa Like a Virgin (see above). Hey, it beats being a Slutty Pirate. —The Fug Girls
