Part of the fun of Halloween is dressing up yourself, the other part is seeing all of the elaborate celebrity costumes. Stars like Neil Patrick Harris, Heidi Klum and Beyoncé are known for going all out for the occasion and, once again, they did not disappoint.

Klum looked like royalty at her at her 19th Annual Halloween Party in New York City on Wednesday. The “America’s Got Talent” judge transformed into Princess Fiona from “Shrek” with help from some prosthetics. She shared the whole process on her Instagram to show followers exactly what it took for her to become the ogre. Her boyfriend, Tom Kaulitz, went at the franchise’s titular character.

Last year, Beyoncé channeled Lil’ Kim for Halloween in five different costumes, and for 2018, she chose another iconic artist. She recreated Toni Braxton’s “Another Sad Love Song” single cover, with one main difference. Her name wasn’t Toni Braxton in the recreation, it was Phoni Braxton. Beyoncé did the same thing for Braxton’s “Toni Braxton” album cover.

One 2018 Halloween costume wasn’t enough for the singer, though. She also dressed up as American track and field star, Florence Griffith Joyner, also known as Flo-Jo, for the holiday. Jay-Z was an athlete for the occasion, as well. Beyoncé shared a photo of her in costume next to the rapper dressed as Tommie Smith.

As for Harris, he and his family once again proved why they’re the royal family of Halloween. This year, they took to the cemetery for a creepy photo shoot of their hitchhiking ghost costumes from Disney theme parks’ Haunted Mansion.

One day of costumes wasn’t enough for celebrities, though. Many started up with the Halloween fun before the spooky holiday had even officially arrived. Over the weekend, stars donned their best get-ups and celebrated the holiday at different parties, including Just Jared’s Annual Halloween Party in Los Angeles.
