The best celebrity Halloween costumes of 2021

Celebrities were really feeling the spirit this year as they unveiled their costumes for All Hallows' Eve. To start, the team at NBC's Today show put on a Football Fright in America for their big 2021 Halloween episode. Hoda Kotb dressed as Carrie Underwood, who performs the theme song for Sunday Night Football. Savannah Guthrie and Jenna Bush Hager came out as cheerleaders, while Al Roker and Sheinelle Jones channeled past Super Bowl Halftime performers, the Weeknd and Bruno Mars, respectively. Click through to see other stars — including Harry Styles, Lizzo, and Cardi B — serving their craziest, creepiest looks.

Carson Daly and Willie Geist turned out as athletes for the Today show event. Daly portrayed Rob Gronkowski, while Geist dressed as Tom Brady. 

Ryan Seacrest and Kelly Ripa pulled out all the stops as usual during their Halloween episode, including one bit where Ted Lasso had tea with one of the Bridgerton siblings.

The Live With Kelly and Ryan cohosts also dressed as Beth Harmon from The Queen's Gambit.

Let's get physical! Ripa channeled Jane Fonda from her popular workout videos in the '80s.

Meanwhile, Judy Greer channeled Diane Keaton in Annie Hall. La-di-da, la-di-da...

Idris Elba and his wife, Sabrina Dhowre Elba, got into the spirit at Annabel's Halloween Party in London. 

So did actor Micheal Ward (The Old Guard), who was all smiles in his devil horns and Pac-Man suit.

It was hard to tell Princess Maria-Olympia of Greece and Denmark and model Ella Richards (the granddaughter of Keith Richards) apart since they were dressed as the twins from The Shining. 

Ellen DeGeneres dressed as her future self during The Ellen DeGeneres Show's last Halloween episode ever. "I decided to go as Future Ellen," she told her audience after rolling out on a tricked-out motorized scooter. "This is my future. Apparently, this is what my writers and costume people think I will look like in the future."

DeGeneres' sidekick tWitch followed suit, envisioning what he might look like when he's 79.

Who ya gonna call? Kelly Clarkson, actually, 'cause she's suited up as a Ghostbuster for The Kelly Clarkson Show.

Talk show host Tamron Hall had a very specific costume this year. She played supermodel Naomi Campbell, but particularly Naomi Campbell when she fell on the runway during a Vivienne Westwood fashion show in Paris in 1993.

Drew Barrymore took viewers on a time-traveling journey through different eras with multiple costume changes for The Drew Barrymore Show. First stop: The 1920s, where she rocked this 1920s' flapper look alongside frequent guest Ross Mathews' Charlie Chaplin.

Barrymore was totally '80s as Madonna, circa "Like a Virgin," while Mathews made for a perfect Boy George.

Representing the '90s, Barrymore and Mathews disguised themselves as a grunge couple from Seattle.

And Underwood brought out an NFL quarterback Lamar Jackson costume. 

Kloots also channeled ice skier Lindsey Vonn. 

The View went with a Broadway theme for their 2021 Halloween show — The Viewsical! Whoopi Goldberg made a hilarious, hungry Audrey II from Little Shop of Horrors.

As Eva Perón, Ana Navarro lip-synced "Don't Cry for Me Argentina" from Evita to kick off the broadcast.

Joy Behar found herself doing the "Time Warp" as Magenta from the Rocky Horror Show.

Sara Haines made for a sexy Satine from Moulin Rouge.

Sunny Hostin took center stage look as Deena Jones from Dreamgirls.

Ricki Lake is a bad, bad girl for keeping this moment from her fans for 34 years! The 53-year-old actress wore Tracy Turnblad's dress from John Waters' classic musical Hairspray for the first time since shooting the movie in 1987 during her appearance on The View.

Rachael Ray and her husband, John Cusimano, made for a couple of cute party animals while whipping up some treats on the Rachael Ray Show.

Lizzo summoned the Force (and the green face paint) to perform in full Baby Yoda regalia at the Spotify Ghost Town Halloween Party in West Hollywood on Friday.

Paris Jackson tapped into her artistic side for Halloween, slapping on a ginger beard, paint splatters, and an oversized straw hat to channel Post-Impressionist Vincent van Gogh. Jackson, who attended her brother Prince's L.A.-set Thriller Night Halloween party, also wore a patch depicting van Gogh's severed ear in a jar.

Harry Styles gave concert-goers and fans a treat during Halloween weekend. Performing at Madison Square Garden on Saturday, the singer appeared on stage in a Dorothy costume complete with a blue dress, a bow, and of course, sparkling ruby slippers. He even had a basket with a stuffed Toto. Not to be outdone, Styles' bandmates also joined him in elaborate Wizard of Oz get-ups.

Steve Buscemi proved he knows how to do Halloween right — by paying tribute to his own meme. The actor trick-or-treated in his Brooklyn neighborhood and dressed up as his memorable skateboard-wielding character from an episode of 30 Rock in which he went undercover and tried to fit in with a group of high schoolers, asking them, "How do you do, fellow kids?"

The Weeknd always goes all out when it comes to costumes, but the Canadian was almost unrecognizable this Halloween as Don Vito Corleone from The Godfather, the character originally played by Marlon Brando.
