Miley Cyrus

Ever the provocateur, pop princess Miley Cyrus poked fun at her own MTV VMAs controversy by dressing as rapper Lil' Kim from the '99 VMAs-- revealing boob pastie included.

Kate Upton

The buxom blond model attended a Halloween party in Beverly Hills on Oct. 25 dressed as... a fancy skeleton? Your guess is as good as ours.

Matt Lauer

This is seriously spooky: 'TODAY' co-host Matt Lauer dressed as Pamela Anderson's busty 'Baywatch' character, C. J. Parker, during a taping of the show on Oct. 31.


Chelsea Handler

Ever the cheeky prankster, E! late night talk show host Chelsea Handler dressed up as a cheery pregnant woman for Halloween earlier this week.


Are you ready for this jelly? She's got over seven million followers on Instagram, so pop diva Beyoncé decided to dress as, you guessed it, an Instagram of herself.


Fergie & Josh Duhamel

The husband and wife duo of Fergie (of The Black Eyed Peas) and Josh Duhamel really got into the Halloween spirit this year, dressing as a cleavage-heavy Elvira and the ghoulish Riff Raff.

Larry David & Pal

Even Larry David, the famously grouchy 'Curb Your Enthusiasm' and 'Seinfeld' creator, got into the Halloween spirit this year. Here he is dressed as a two-headed man (along with an unidentified pal) attending the Casamigos Halloween Party at the home of Mike Meldman on Oct. 25 in Beverly Hills.

Kelly Ripa & Michael Strahan

Not to be one-upped by Matt Lauer and the 'TODAY' team, 'LIVE with Kelly and Michael' co-hosts Kelly Ripa and Michael Strahan dressed as Miley Cyrus and Robin Thicke from the MTV VMAs. A pretty unimaginative choice, but they sold it pretty well.


Chris Colfer

The 'Glee' star Instagrammed this photo of himself dressed as everyone's favorite bleep-bleepin' robot: R2D2, from 'Star Wars.' Although we don't remember metallic little fella ever dressing like this in the movies...


Paris Hilton

Paris Hilton dressed as Miley Cyrus at the VMAs. Again, not very imaginative... but some points for vividly recreating the costume.


Neil Patrick Harris & Family

Every year, the Harris clan dresses in amazingly cute getups. They are, without question, the first family of Halloween.


Sir Patrick Stewart

The 'Star Trek' and 'X-Men' actor has become one of the funniest voices of Twitter. On Halloween, he tweeted this photo of himself dressed as a lobster in his Brooklyn bathtub.

Sandra Bullock

Now that she's back from space, the 'Gravity' star took her son, Louis, trick-or-treating in matching skeleton costumes. Cute.
