Halloween

Heidi Klum's incredible Halloween party is like an onion -- it's got layers of awesomeness, baby -- starting with the fact she rocked an amazing "Shrek" costume ... in front of Mike Myers!!!!

Klum used a team of makeup artists and prosthetics experts to put together a super detailed Princess Fiona getup ... and after hours and hours of prep, the big reveal TOTALLY DELIVERED!

Of course, Heidi's boyfriend, Tom Kaulitz, went as Shrek -- and when Mike Myers (the VOICE of Shrek) turned up, they had to bring him in for a photo.

The party was a huge hit -- with some guests even copping a feel of Fiona's giant fake boobs (with consent).

It all went down at Lavo Nightclub in NYC -- with a crazy guest list that included everyone from Mel B to Ice-T to Neil Patrick Harris, Questlove and Zac Posen.

The Weeknd and Bella Hadid went as Beetlejuice and Lydia. Kat Graham went as The Mask. Harry Connick Jr. trotted out his New Orleans Saints uniform.

There were sexy people. Scary people. And, funny people.

And, while we LOVE Daymond John, dude went in a simple skeleton jumpsuit -- COME ON, MAN!!!!

Bradley Cooper and Kate Hudson aren't about that Hollywood bar scene -- scoring candy bars with the kiddos is more of their thing.

Bradley and Kate teamed up on Halloween in Brentwood for a little trick-or-treating ... with Kate's BF, Danny Fujikawa, also in tow. Bradley sure got in the spirit with a bear costume as he happily carried his 1-year-old daughter, Lea, on his shoulders.

Hard to tell what Kate and Danny were going for -- comfy PJs maybe? Anyway, their daughter, Rani, is only a month old -- too young for candy hunting -- but they ushered some other kids ... probably relatives. Knocking on a door with 2 huge movie stars behind ya has to help score better candy, right?

Hopefully no candy corn. #WorstHalloweenCandyEver

It's kinda terrifying ... Halloween's officially behind us but luckily these celebs went all out for one last scary ass bash in 2018.

Halsey, Rihanna and Emily Ratajkowski are just a few of the celebs who brought their best on Halloween night. Halsey was a spooky, but very sexy, cheerleader when she hit up Delilah in WeHo. Emily was also there ... and give her a damn hand 'cause she knocked it outta the park channeling her very sexy Raquel Welch.

RiRi was across the pond doing her thing ... busting out Catwoman gear at Annabel's in London. Did we mention it was very sexy? The Weeknd and Bella Hadid killed with their couples outfit, and Fergie went full Pink Ranger.

The stars of "Flipping Vegas" got someone flippin' pissed at their Halloween stunt -- riding horses on the beach -- and they ended having a run-in with Johnny Law.

Scott and Amie Yancey hit Malibu Tuesday evening on horseback while in costume -- Scott was the Headless Horseman, and Amie looked like Daenerys from "Game of Thrones." As you can see in the video ... onlookers at the Sunset Restaurant were in awe, but eventually ... the party on hooves was stopped in its tracks.

Scott's rep tells us cops arrived shortly after the couple trotted their steads down Westward Beach Road and told them they couldn't ride on the street.

Their costumes must have impressed the officers, because they were merely escorted to the trailers where the horses were stowed. Their show's been off the air since 2014, but seems like they still have fans in law enforcement -- Amie and Scott were allowed to go on their way ... on foot.

If the calendar says Oct. 31, TMZ staffers are dressing to the nines to honor the best (and sometimes worst) pop culture moments -- and these costumes slayed, if we do say so ourselves. And we do.

We had everyone from Conor McGregor and Khabib Nurmagomedov, Ariana Grande and Pete Davidson (pre-split), Prince Harry and Meghan Markle ... and Tonya Harding and her ma, LaVona Golden.

These were just a few standouts, but check out the gallery to see the rest -- including Bert and Ernie, Freddie Mercury (guess who dared), Tekashi69, bruised Cardi B and a very realistic Grinch and Cindy Lou Who.

Hollywood knows how to do Halloween ... it's like they've got a sixth sense for this based on the outlandish 2018 costumes.

Celebs were in the mood to throw on their best getups for tons of Halloween parties this year ... like Christina Milian getting decked out in pink Hello Kitty gear for the Galore Magazine party. Ciara repped Wakanda well with an elaborate "Black Panther" costume at a Bacardi bash in NYC.

Meanwhile, Bella Thorne nailed Chucky's bride Tuesday night in Los Angeles.

If the horror's too much to swallow ... check out the gallery for Elsa Pataky and her kids trick-or-treating or Cristiano Ronaldo getting his fam in the spirit. 'Memba when Halloween was for kids?

If you've got love for Marlon and Shawn Wayans going full whiteface, then feel free to do the same on Halloween ... according to their nephew, who is hysterically tiptoeing around the subject of race and costumes.

We got Damien Dante Wayans outside L.A.'s Sunset Plaza and asked him about 2 specific costume ideas -- "White Chicks" and "Black Panther." DW told us he appreciates people paying homage to his uncles' cult classic flick, but you gotta see his reaction when we brought up "Black Panther."

As our photog put it ... the Marvel movie was huge this year, and lots of people -- black, white and otherwise -- are feeling inspired. Well, Damien seems to be giving Panther costumes a thumbs-up too ... verrrry nervously, though.

Just watch. The takeaway -- put whatever on your face today, but do it respectfully.

The haunted box that seemed to curse Post Malone is about to see the light of day on Halloween, 'cause its new owner wants to take a peek inside ... but on one condition.

"Ghost Adventures" star Zak Bagans tells TMZ he plans on opening the dybbuk box in his Haunted Museum Wednesday night, and he'll be doing it live on his show. As crazy as that sounds, it's even worse when you hear what Zak's been going through lately.

He tells us he's been getting ominous signs left and right leading up to the event that would make even Damien Thorn shake. It's pretty freaky sh*t -- stuff like dreams about people and animals being killed, calls from an unknown number telling him people will die ... and illness plaguing him for the past few weeks.

Remember ... this is the same box that supposedly put Post Malone's life in danger these past few months after he was in the same room with Zak, who ended up touching the thing. Post didn't touch it himself, but he did touch Zak's shoulder ... and Zak says that's enough to trigger a curse.

There is an upside, though, that hopefully keeps Zak from prying this devil box open. He tells us he'll only do it if he does NOT feel the same supernatural sensation he and Post felt in the room this summer.

Considering this box has made people pass out on sight -- like this poor woman here -- we're guessing he'll feel something. BTW ... we're told this lady collapsed after coming into the same room with the box just a week after Post visited. She had to be taken to the ER.

Kate Hudson's catching some flak for dressing up as a follower of Bhagwan Rajneesh -- the cult leader in the Netflix docuseries, "Wild Wild Country" -- but one of his former disciples LOVES it.

We talked to Philip Toelkes -- who used to go by Swami Prem Niren when he served as the top attorney for the controversial Rajneeshpuram in the '80s -- and he tells us Kate and her friends were well within their rights to celebrate the group.

Kate faced backlash online after posting the pic, apparently at a Halloween party, because some people felt she was glorifying the "cult."

Let's face it ... Rajneeshees will be a hit Halloween costume this year -- with the popularity of the Netflix series -- and Phil says he's totally on board with that. He also thinks Bhagwan -- aka Osho -- would be too, as long as it's respectful.

Phil also took aim at the haters, who say the Rajneeshees almost ruined a way of life for many Oregonians, saying they never understood their movement.

On the other hand, the mayor of Antelope, OR -- which had been overrun by the Rajneeshees -- tells us, "They plotted to assassinate someone. How friendly would others be if [someone] dressed up as a terrorist for Halloween?"

How does Ben Stiller feel about Shaun White getting heat for an offensive Halloween costume based off his "Tropic Thunder" movie?

He's sorry. Still.

TMZ Sports broke the story ... White dressed up as Simple Jack -- a mentally disabled character who was constantly referred to as the r-word in the 2008 movie.

Back in 2008, several disability groups spoke out against the flick -- calling the Simple Jack character offensive and tasteless.

Now, with White trotting out the costume again, groups like the Special Olympics ripped Shaun for exploiting special needs for a cheap laugh.

White has since apologized -- and now Stiller is weighing in too.

"Tropic Thunder was boycotted 10 years ago when it came out, and I apologized then," Stiller said on social media.

"It was always meant to make fun of actors trying to do anything to win awards. I stand by my apology, the movie, Shaun White, And the great people and work of the Special Olympics.

It's the day before Halloween and Tom Brady still has NO IDEA what his costume's gonna be ... but TB12's keepin' calm in the pocket, 'cause he's leaving it all up to Gisele!!

ICYMI ... the superstar couple went viral with their avocado toast costume last year (which we pretty much assumed was Gisele's idea at the time).

But, Brady came clean during his weekly interview with "Kirk & Callahan" on WEEI about how much he contributed to the couple's outfit selection this year ... and it seems like the dude's been spending too much time in the film room to give much effort.

"I gotta check in with the missus. I don't know what she got," Brady says. "That hasn't been on my radar, unfortunately."

"She got something, so ... I'll ask her today."

Nothin' like a good ole 2-minute drill, Halloween edition, from Brady.

There's more ... Brady was asked about his upcoming match-up with Aaron Rodgers ... and Brady says he's been inspired by the Packers QB.

Pete Davidson finally looks like he's feeling better after his split with Ariana Grande ... 'cause the comedian was grinning like a jack-o-lantern at a Halloween event with his buddy.

Pete walked through a holiday event for kids Sunday on his home turf of Staten Island, and judging by these pics ... the 'SNL' star was happier than a trick-or-treater with a pillowcase full of candy.

Pete was passing through the neighborhood shindig when he stopped to pet a furry pooch and snap a selfie with his fans. We're told he was super friendly to everyone and seemed to be in a very good mood.

It took a few weeks, but Pete is looking way happier than he was the last time we saw him. He really looked like a man down on his luck a few days after we broke the story he and Ariana called off their engagement.

Hey, there's nothing like a pumpkin patch and a cute pup to lift your spirits.

Fabolous got into the Halloween spirit early by rocking an iconic costume from Eddie Murphy's "Coming to America" ... none other than McDowell's employee, Prince Akeem.

The Brooklyn MC found himself in Hollywood Monday night during the unveiling of a McDowell's pop-up restaurant, taking place at Fat Sal's sandwich shop off Highland Ave. Fab definitely didn't skimp on the details for Akeem's McDowell's uniform.

He had the plaid vest, bow tie, hat ... and Akeem's signature mop and bucket. We're told the rapper also checked out the recreated My-T Sharp barbershop next door, that was also featured in the 1988 flick, where he got a tour and took photos with fans.

Fat Sal's will be keeping the McDowell's pop-up open through Halloween, where they're serving up dishes from the movie like The Big Mick, The Sexual Chocolate Shake and Zamunda Fries.

We know when you think Akeem, you might've thought garbage. But after this ... hopefully, you think Fabolous. Dude's outfit is on point! We shot him in McDowell's with the 'stume, and people definitely seemed to be diggin' it.

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!
