UPDATED: Not even Hollywood’s biggest stars can resist some Halloween fun.
Celebrities like Neil Patrick Harris, Beyonce and Heidi Klum got into the holiday spirit and went all out on their costumes. Outfits seemed to be more spot-on than spooky in 2015, with big themes being “Star Wars” and superheroes.
See some of the best costumes, from both Halloween weekend and the parties before, below.
Leave it to Harris to bring the force to his family. Harris, his husband David Burtka and their young children dressed as Obi-Wan Kenobi, Han Solo, Princess Leia and Luke Skywalker, respectively, for a “Star Wars”-themed holiday. Luckily, they can reuse their costumes for a family viewing of “The Force Awakens” when it debuts in December.
Now THAT’S a Jessica Rabbit costume. Heidi Klum didn’t hold back with her costume of the sultry cartoon character, showing off at her 16th annual Halloween party.
It’s little surprise that Miley Cyrus showed up in the creativity department. She dressed as a tooth this year, along with a friend who went dressed as the Tooth Fairy.
It was Katy Perry, however, who dropped the mic — no, really. The popstar went as a piece of equipment she uses quite a bit, donning an elaborate microphone costume.
Gwen Stefani wasn’t just a sexy cowgirl. The No Doubt frontwoman added some blood to her outfit to give the costume an element of spookiness.
Kylie Jenner went for a fierce look this year. With an ensemble reminiscent of Xena warrior princess, a prop and some friends, she was ready to hit the parties (and was to not be messed with).
Leave it to Kim Kardashian to attend Halloween parties as… herself? The star put on her famous 2014 Met Gala dress for the holiday’s festivities.
Channing Tatum and Jenna Dewan Tatum have arguably laid claim to the best couples costume of 2015. The duo dressed as a pair of Cats-in-the-Hat.
Does it count if an actor dresses up as a superhero he’s already playing? Either way, Ryan Reynolds stole the show with a Deadpool costume, but he had some friends to an X-tra element to the outfit.
While there were no doubt many dressed as Justin Bieber himself this Halloween, the singer went the classic route, putting on a wig for a Jackie Moon costume.
Jessica Alba teamed up with her friend model Kelly Sawyer to reenact a classic. The team donned some iconic dresses to become Romy and Michelle.
Allison Williams was looking pretty as Belle from “Beauty and the Beast,” with full makeup and hair and a blue dress to look just like the Disney character.
If this isn’t a fitting costume, what is? The Rock got to put his muscles to good use in dressing up as Popeye, and even nailed the facial expression.
Beyonce, Kelly Rowland, Serena Williams and La La Anthony attended Ciara’s birthday party in festive attire. The “Run The World” singer donned a white wig and some spooky contacts to become X-Men’s Storm. Ciara appeared as Batgirl alongside Rowland’s Catwoman and Anthony’s Wonder Woman costume.
Russell Wilson also participated in wearing a costume to the singer’s Halloween bash. The football player suited up as The Dark Knight with his partner in anti-crime Batgirl.
The cast of “Grandfathered” came together at Maxim’s annual Halloween event. John Stamos and Josh Peck took a “like father, like son” approach in matching devil costumes.
Colton Haynes is nearly unrecognizable as Ursula, the Sea Witch, from “The Little Mermaid.” The “Arrow” star underwent professional prosthetic makeup to pull off the evil look.
Miranda Kerr glamoured up as Marilyn Monroe. She dressed as the late starlet in her most famous look in 1955’s “The Seven Year Itch.”
Nick Jonas arrived to Maxim’s party the MacDonald’s Hamburglar. He later performed in his costume as the classic sandwich bandit.
Robert Downey Jr. left his Iron Man costume at Stark Enteprises to trick or treat in something a little more cozy. The “Iron Man” thesp was channeling his inner tiger before posting this photo to his Instagram page.
Niecy Nash and Aubrey O’Day were covered all in fur at the Maxim party. The actress looked cozy in her feline costume alongside the Danity Kane singer’s Cruella de Vil.
Chrissy Teigen posed as Food Network’s Guy Fieri on the set of “The FABLife.” The supermodel went as her food expert peer in a special Halloween episode of her daytime talk show.
“Revenge” alum Ashley Madekwe did a spot-on impression of Uma Thurman’s character, Mia, in “Pulp Fiction.” The actress captured the horror in the scene, where Mia was close to dying from a drug overdose.
Kevin Durant paid homage to Martin Lawrence with his costume choice. The basketball star went as an undercover detective Miles Logan from the 1999 comedy, “Blue Streak.”
Kourtney Kardashian also felt super powerful as Wonder Woman. The reality star coordinated with tykes that also dress as fantasy characters for the occasion.
