Halloween

Hailey Bieber and Kendall Jenner are trading in Hollywood for "The Simple Life" ... or, at least, they are for Halloween.

The supermodel and the Rhode Skin founder channeled Paris Hilton and Nicole Richie from their 'Simple Life' days for Halloween ... going so far as to recreate one of the show's most iconic scenes.

Check it out ... Justin Bieber's wife is dressed as Nicole, wearing denim overalls and a pink bra while holding a pitchfork. Next to her, Kendall sports a little denim skirt and halter top while holding a puppy ... bringing to life the reality show's famous poster.

Kylie Jenner's bringing all the Demi Moore vibes this Halloween, totally nailing one of the star’s most iconic photo shoots.

Take a look -- Kylie went all in, recreating Demi's legendary "Striptease" pose from '96, with one leg crossed to cover herself, serving major sultriness right at the camera.

Kylie's giving full-on throwback -- windswept brunette locks, smoldering stare, every bit the spitting image of Demi's iconic look.

Celebs definitely threw some money at their Halloween costumes this year, and to avoid the paparazzi and camera craze ... stars hired their own crews to hard-launch their spooky looks ... and it's all for the 'Gram!

Full-on photo shoots went down for Christina Aguilera, who slayed as Stoker's 'Dracula,' while Keke Palmer stepped up to the throne with her son as Cersei Lannister from "Game of Thrones."

"Beetlejuice" was a fave among stars like Vanessa Bryant and James Charles ... both giving their own renditions and killin' it in the makeup department.

Lizzo crushed the Halloween game this year -- leveling up with several costumes such as a mighty mash-up of Edward Scissorhands and SZA, AKA "Edward SZA Hands."

The singer also painted her entire bod bright red and donned a voluptuous "hunny bunny" body suit corset. She topped off the look with a long blue wig.

She swiped this "Face Card" credit card costume on her social media ... A shoutout to Beyoncé's "Heated" from Bey's 2022 Renaissance album. The Yitty shapewear owner rounded out the costume with a black jumpsuit and held on tightly to some Chanel shopping bags.

The winner of the most adorable Halloween costume goes to ... Dave Portnoy's pups, Miss Peaches and Pete, whose outfits were inspired by WNBA superstar Caitlin Clark!!

Portnoy showed off his famous doggos fit, along with her new adopted brother Pete The Beagle on All Hallows Eve ... with Miss Peaches rocking a Clark jersey with a black wig -- while Pete played the role of the basketball!

The fit even caught the attention of the person who inspired it ... with Clark dropping a comment showing love for Peaches hairpiece!

Paris Hilton's giving fans a sign ... posting pics of herself on Instagram dressed as her close pal Britney Spears -- holding a diary that reads "Bad Bitch" across the cover.

The reality TV star shared several photos of her "...Baby One More Time" inspired outfit ... gray sweater and matching mini-skirt, and a white button-down shirt tied at the bottom to show off her tanned, toned stomach.

Check out the photos ... Paris is putting some cleavage on display -- posing with several sultry looks while leaning back on bright pink lockers. Brit's music vid is a bit more gray than Paris' interpretation, but ya know Hilton had to include her signature color for her shoot.

The celebs are going all out for their Halloween 'fits, and we're rounding up the best costumes from this year's spooky season! Hope your trick-or-treat buckets and bags are empty, 'cuz we're about to fill you up with some Halloween goodies!

No question Tyga had a pro team help pull off his "Tales from the Crypt" look, but he absolutely crushed it, while Alix Earle fully committed to her Cheshire Cat transformation -- posing on a magic shroom 🍄!

The Chainsmokers, Andrew Taggart and Alex Pall, cooked up a spot-on rendition as Remy Ratatouille and Linguini ...

Step aside Sabrina Carpenter and Jenna Ortega, because Madi Monroe and Avani Gregg nailed Sabrina's "Taste" music video impersonation.

And once and for all, click your heels 3 times for Olivia Culpo and Christian McCaffrey's "The Wizard of Oz" costumes!

Rob Kardashian's daughter Dream is proving to be quite the Los Angeles sports fan ... dressing as the late Kobe Bryant for Halloween 2024.

The reality TV star posted his 7-year-old's getup on Instagram Thursday, making it clear the little one's tribute to the NBA legend got his stamp of approval.

In the upload, Dream is wearing Kobe's jersey, decked out in head-to-toe Lakers gold ... even practicing her free throws in a couple shots.

Spooky season is going out with a bang at the TMZ office ... and our staff is pulling out all the stops for Halloween, with costumes from the biggest moments of the year in pop culture ... and some classics too.

Post Malone's getting a shout-out ... and we've got his favorite NFL team covered, with a trio of Dallas Cowboys cheerleaders.

Shawn Mendes is getting into the Halloween spirit ... putting up some last-minute decorations at his Los Angeles home ahead of the spooky holiday.

Check it out ... the singer, with the help of his sister, Aaliyah, draped the front yard of his L.A. pad in fake cobwebs Wednesday ... getting the abode ready for the slew of trick-or-treaters set to hit the streets Thursday evening.

As to why Shawn waited so late into October to decorate, it's safe to assume his tour -- which had him on the road for most of this month -- factored into his decorating plans.

Forget the kids, La La Anthony's feeling the real spirit of Halloween ... which is all about grown-ass celebs slipping into scary, sexy, cool costumes and packing into fancy West Hollywood parties.

La La hosted her bash at LAVO on the Sunset Strip, and her famous pals didn't disappoint showing out in some outrageous getups.

Anthony -- who dressed as Lady Deadpool from this year's uber-popular "Deadpool & Wolverine" -- was joined at the party by the likes of Karrueche Tran and Winnie Harlow ... both outfitted in glamorous white dresses.

America's morning TV hosts are kicking off Halloween with their wildest, creepiest costumes ... and, as usual, the crew over at NBC's "Today" show went all out.

Dylan Dreyer kept the "Beetlejuice" vibes going, diving into character as Winona Ryder’s Lydia Deetz -- goth 'tude and all!

The White House Halloween Party featured tons of kids in costumes ... many of whom got to meet -- and were nearly eaten -- by the President of the United States.

The event went down Wednesday night ... and, like we told you, it received some side-eye from the right when President Joe Biden leaned in and pretended to take a bite out of a baby's leg. The kid was dressed as a chicken, to be fair -- but, that did little to slow the spread of the image on social media.

Turns out this wasn't the only time JB was feeling famished ... pretending to bite the foot of a different kiddo and kissing a couple other babies on the cheeks.

Bill Belichick-themed Halloween costumes are clearly in this year -- not only are his current and former lovers dressing up as him for the October holiday ... so is his colleague, Ryan Clark!!

The former Pittsburgh Steelers safety rocked a realistic Belichick 'fit while appearing on Wednesday's episode of "Inside the NFL" ... complete with a wig and, of course, a cut-sleeve Patriots hoodie.

Clark did an impression of Bill while in the get-up too -- going off on a bit of a "Do your job!" rant to open the show.

Before they were superstars, these adorable kiddos loved dressing up for Halloween, but can you tell who these celebs are -- back before they were in front of the flashing lights?

Demi Lovato, Kendall and Kylie Jenner and Ethan Slater are just a few of the lil' tykes who sported a cute costume back in the day -- but good luck guessing which one is them!

This actress is known for her thrilling work in horror movies ... some may even deem her as the ultimate "scream queen!" But is this witchy gal who you think it is?

Even as a dressed-up princess, this singer couldn't "ignore the crazy visions of her living in LA" one day ... Can you guess who she is?

President Joe Biden had some light-hearted fun when he playfully pretended to chomp on a baby dressed as a chicken during a Halloween celebration ... leading some on social media to fly off the rails.

Here’s the deal … the White House hosted a fun little bash on Wednesday with several kiddos sporting their adorable costumes, with one in particular … a baby dressed as a chicken carried to Biden by mom.

With a smile on his face, Biden pretended to take a little nibble ... and, the baby giggled but a snapshot of the moment made it look far more intense … and, that quickly spread on social media like wildfire.
