Halloween

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.

Hoda and Jenna were headed straight into "Titanic" waters as Jack and Rose, while Al Roker summoned his inner "Beetlejuice" -- and yeah, he nailed it!

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.

The Menendez brothers are on a roll lately with a possible chance at future freedom -- and TMZ has the low-down on what could be their final Halloween in the slammer.

A source within the California Department of Corrections tells TMZ ... Erik and Lyle are all set for a Halloween movie night in the clink, where they’ll likely be cozying up to the OG 1990 version of Stephen King's "IT."

We're told the bros and their cell block buddies at the Richard J. Donovan Correctional Facility in San Diego are whipping up a classic prison treat for the occasion -- "candy salad," which is basically a mixed bag of every candy available in the commissary thrown into one giant bowl.

The former home of the Menendez brothers is going to attract a lot of peeps looking for some Halloween creeps -- but another house in Beverly Hills is expected to be a way bigger spooky draw ... as far as cops are concerned.

The house where Erik and Lyle Menendez brutally murdered their parents has been a hot destination for lookie-loos for the last several weeks thanks to wildly popular Netflix specials ... and police have been inundated with calls from angry neighbors.

Cops tell TMZ on the eve of Halloween they expect the affluent block to be a mess with a ton of foot and car traffic ... but they will be keeping a closer eye on The Witch's House, about a mile and a half away, where they assume far more people will visit -- increasing the odds of bonehead antics. Police will have a presence there all day into the night, we're told.

Saweetie is all for her fans dressing up as her for Halloween, but she's going a completely different route with her costume ... Heath Ledger's Joker!!!

The "Tap In" rapper went full Clown Princess of Crime Wednesday when she digitally inserted herself into the classic film "The Dark Knight" as The Joker ... y'know, the part where Michael Jai White's character had to pick his mans up!!!

Her makeup, mannerisms and hunched posture were all spot-on ... Heath famously won an Oscar for his performance -- Saweetie's future looks bright!!!

Zak Bagans is planning to take his "Ghost Adventures" team to the famous "Poltergeist" house for his next in-person investigation ... TMZ has learned.

The paranormal expert tells TMZ ... his team will be heading to the Simi Valley, California home -- which was featured heavily in the horror classic -- in mid-November, with plans to investigate some of the spookier aspects of the abode.

Zak says their preliminary research shows the new owner got badly affected by something from inside the house ... and that the homeowner specifically reached out to them in the hope of getting answers.

Kylie Jenner's Halloween costume is out of this world ... 'cause she posed for a hot photo shoot as '60s sci-fi legend "Barbarella"!!!

The model/mogul posted several pics of her as the vintage character on her Instagram Wednesday morning ... first posing in a silver top with a white silk skirt -- and baring her toned stomach as she looks off into the distance.

Another shot captures the youngest KarJenner sister in a strawberry-blonde wig -- blaster in hand, elbow resting on a stocking-covered leg.

Jordon Hudson hit Disney World this week with friends for one of their engagement celebrations ... and given that All Hallow's Eve is Thursday -- she and her gal pals decided to rock costumes during their day at Mickey's place.

For her 'fit, Hudson paid homage to her 72-year-old boyfriend ... emulating a look he once wore when he was an assistant on the New York Giants' staff back in the 1980s.

Christian McCaffrey apparently can't have a little Halloween spirit while he nurses his injury ... 'cause the 49ers superstar adorably showed off his couples costume with his wife, Olivia Culpo -- and fantasy football owners ain't having it.

In fact, they got their adorable pup, Oliver Sprinkles, to be Toto!!

Greg Nicotero, one of the masters of Hollywood's goriest special effects makeup, is spilling his top tricks to get you ready for Halloween -- using stuff from your own home!

Greg shared some seriously creative tips that we never even thought of ... including one food staple you can use to go all-out with your zombie face makeup.

Halle Berry films were top of mind for Coi Leray, Halle Bailey and Tyla this Halloween -- they all reimagined the Oscar winner in completely different costumes!!!

On Wednesday, all 3 superstar artists released their Halloween photoshoots at noon EDT sharp ... though it doesn't look to be a coordinated effort -- more like a coincidence.

Coi morphed into Halle's cult-classic "Catwoman" -- perfect stitching, cowling poses and all!!!
