The stars begged for it! You loved it! So it's time for another edition of our smash hit photo game: Halloween...or Real Life?
First we have that lady George Clooney's dating, and she looks lovely in a black lace mask and matching Peter Som frock. Her name is Stacy Keibler, but shhh! Don't tell! She's in disguise!
We also have 90210 starlet Shenae Grimes lurking behind a pair of Walking Dead zombie contacts, as well as Nicki Minaj dressed like a terrifying hybrid of zebra mixed with Adam Lambert.
But who among these celebs has Halloween as an excuse?
Keibler's mask was part of a look she wore to host a masquerade ball at Hyde Bellagio this weekend in Las Vegas. Grimes? Yep, that's also a costume, and she's dressed as Monster High's Frankie Stein—how cute is that?—on her way to Matthew Morrison's 3rd Annual Halloween Party.
As for Minaj, well, she never needs an excuse to dress like this. Every day is Halloween for her. But if you want the details, this was her outfit for a party hosted by MAC Cosmetics in London, and Halloween had nothing to do with it.
