And Now For All The Other Celebrity Halloween Costumes Of 2012

Was Chloe doing research for her new zombie movie Maggie? Probably not, since here she's a sexy zombie; note the many buckles all over her ensemble. Still, being Chloe, she kept it as tasteful as ever. And I'm digging the eye makeup!

I preferred Diddy as Prince, but I guess this was a more relevant pop culture costume. The only annoying part was his charming caption: "Happy Halloween bitches! Suck my dicktator!"

This could be my favorite costume that Katy Perry has ever worn simply because of the accuracy. You probably recognize her as Jane Lane, Daria's best friend from the MTV animated series. From the piping on her jacket to that unmistakable hairstyle, she's got every detail down. Yep, Halloween is made for folks like Katy.

OK, it cannot be coincidence that two celebrities would choose to be Sandy from Grease right as a tropical storm of the same name was bearing down on the opposite end of the country... right? LeAnn's couples costume with husband Eddie Cibrian at least makes some sort of sense, but I'm not sure about the next one.

Yep, that's Gwen as a "bloody Sandy from Grease." Maybe I'm being oversensitive after the hurricane, but it seems like it's in poor taste.

Gotta love a director with a dry sense of humor: "My Halloween outfit. I messed up and cut off the wrong ear....that's why I need researchers 4 my movies."

I'm surprised that Paris Hilton even knew who Batman and Robin are.

As we learned from the VMAs, Kevin Hart gives it his all. Which is why I really liked him as the embodiment of the '70s.

Avril doesn't seem too bothered by her ex Deryck Whibley dressing up as her, as she went out as a sexy sailor. But with that wig, she actually brings to mind Jennifer Love Hewitt on The Client List. Would've been a better costume, IMO.

You rock that cat outfit on your birthday, Jenny McCarthy.

RiRi didn't bother with a costume and just threw on a tiara. Woman after my own heart.
