Halloween

Halloween is the perfect time to get into some crazy characters ... luckily Hollywood is full of them, and there's really nobody else that can pull off an A-list costume better than another celebrity and their good looks!

Scroll through our gallery of stars like Paris Hilton as Miley Cyrus, Kylie Jenner as Christina Aguilera and Beyonce as Lil' Kim to see which stars switched up their famous facades for the Halloween season.

3:58 PM PT -- Shaun White has pulled the photo of his "Simple Jack" costume off of his social and has issued an apology.

"I owe everyone in the Special Olympics community an apology for my poor choice of Halloween costume the other night."

"It was a last minute decision. It was the wrong one." White says.

"The Special Olympics were right to call me out on it. They do great work supporting so many tremendous athletes and I am sorry for being insensitive. Lesson learned."

Shaun White is under fire from special needs parents AND the Special Olympics over his Halloween costume -- Simple Jack from "Tropic Thunder."

Remember, when the movie came out back in 2008, several disabilities groups blasted Ben Stiller and the flick for the character -- an intellectually disabled man who is repeatedly referred to as the r-word.

Now, 10 years later ... White thought it would be a good idea to trot out the costume for a Halloween party and people are pissed.

In fact, a rep for the Special Olympics tells TMZ Sports ...

"We are truly disappointed that Shaun White, an acclaimed Olympian, would choose this costume which is so offensive and causes so much pain."

"Disability is not a joke nor should it be a punchline. We hope that Shaun White and others learn that this just continues stigma, stereotypes and discrimination."

Others have sounded off on Shaun's IG page -- where he posted the pic.

"I'm not sure if it’s worse that this is an actual movie or that you’d think it’s okay to mock individuals who have disabilities. It’s 2018, man. #spreadthewordtoendtheword #rwordhurts," one person wrote.

Another wrote, "You’re a real POS! Really? At the expense of those who can’t defend themselves?? Hope you’re working on your lame apology speech...I know this will be deleted!! Grow up you douche! #spreadthewordtoendtheword #specialolympics."

We reached out to White's agent for comment -- so far, no word back.

George Clooney and Rande Gerber hosted a wild Vegas Halloween party Saturday night, which began with the 2 men at the controls of a jet that flew partygoers from L.A. to Sin City.

The guys took over Catch Las Vegas and converted the space into a full-on Casamigos experience ... black brick walls, black sparkle Casamigos Tequila glitter barrels ... the works.

The trip up to Vegas looked like an experience as well ... with Cindy Crawford as the space waitress serving drinks.

As for the Vegas party ... lots of stars, including Kendall Jenner, Austin Stowell, Joey Fatone, Jermaine Dupri, JB Smoove, Wolfgang Puck, Karolina Kurkova, Marlon Wayans and Steve Aoki. Catch owners Mark Birnbaum and Eugene Remm were also in attendance.

Halloween in Hollywood means everyone is dressed to impress ... but it's up to you to decide which famous look takes the costume crown!

We've collected a bunch of your dressed up pets like cops, ghosts, witches and even real housewives for your Halloween viewing pleasure.

Actor Kobie "DJ K-LUV" Randolph says he was attacked at George Clooney's Halloween party, and depending on who you believe ... Brandi Glanville either broke it up or attacked him.

Randolph told cops Brandi was with a woman with whom he had a past relationship. He claims the woman attacked him, punching him in the face and splitting his lip.

Brandi told cops she broke up the fight, but he says she was one of the perps who attacked him.

Randolph also claims the 2 women attacked him with "12 uppercuts like I'm in a boxing match." He also complained no one at the party came to his rescue.

Halsey looks like she's doing just fine post-breakup with G-Eazy ... having the time of her life at her annual Halloween bash.

As you can see, Halsey went with a Gotham City villains theme ... dressing as Poison Ivy. She danced the night away in L.A. at The Majestic Downtown, sharing the floor with Two-Face, Bane, and The Penguin ... no need for G-Eazy.

As we reported ... Halsey and G-Eazy split this week for the second time this year in their on-again, off-again relationship.

Tons of celebs hit up the annual Casamigos Halloween party Friday night ... and it did not disappoint.

The soiree was hosted by Casamigos founders George Clooney and Rande Gerber at the Bev Hills home of Mike Meldman ... a developer and tequila tycoon.

George was a no show, but there were plenty of stars, including Brandi Glanville, Cindy Crawford, Dave Grohl, Harry Styles, Paris Hilton, Diddy, Zoe Kravitz, Seth McFarlane, Nicky Hilton, French Montana and Ryan Seacrest.

The bash offered up some good grub ... Kobe cheeseburger sliders, truffle fries, chips and fresh guac and pizza. And of course ... Casamigos ice shots and Margaritas.

Don't let these two almost identical images of Heidi Klum freak you out ... Clown around a bit and see if you can figure out the differences between these two spooky snaps!

9:26 AM PT -- A rep for Costume Agent, which originally created and distributed the controversial Caitlyn costume, tells TMZ they're not yanking it from their own site, and certainly not discontinuing it ... backlash be damned.

We're told the 'stume is one of their best sellers -- it's the #6 overall bestseller. Although they have received multiple threats over it this past week, they're standing by their product. The rep says, "It's a costume. It's funny."

A Caitlyn Jenner costume -- which harkens back to her Olympic glory days as Bruce Jenner -- is getting destroyed by critics who say it's insensitive to transgender people ... and it's already being yanked from at least one outlet.

The getup is called "I Am Cait" ... and features a decathlete's jersey with Bruce's number 935, a gold medal and those teeny tiny shorts -- all of that vintage Bruce from his 1976 decathlon victory. However, it also comes with a long-haired wig that's all Caitlyn.

eBay was flooded with criticism for selling the $44.95 costume -- several transgender charities are calling it out as mocking, instead of being an homage.

The caption for one online promo says, "Show your love for Caitlyn Jenner with this awesome adult costume."

The backlash has been enough for eBay to remove the costume, but as of now ... it's still available on Amazon.

The Denver Broncos had a Halloween party ... and man, did it blow.

Von Miller hosted his annual All Hallows' Eve bash for his teammates on Monday ... and the unofficial theme seemed to be people who famously dabbled in the booger sugar, nose candy, devil's candy ... you know, COCAINE!

Check out linebacker Brandon Marshall who transformed into Bobby Brown, complete with a gold chain and king-sized bag of yayo.

Wide receiver Emmanuel Sanders rubbed white powder all over his face to become the legendary "Chappelle's Show" crackhead Tyrone Biggums.

And, not to beat a dead (white) horse ... O.T. Genasis was there performing his drug-inspired anthem, "Coco."

Oh yeah, and Pacman Jones was Boba Fett. Good stuff.
