Instead of going out on a Monday and being a real-life zombie on Tuesday morning, many celebrities decided to celebrate Halloween this weekend. Bette Midler, Katy Perry, Amy Schumer, and Jacob Tremblay already grabbed the spotlight (and headlines) with their killer costumes, but there were other gems to be found.

Musical collaborators and bffs Nick Jonas and Demi Lovato hit the yellow brick road as Dorothy and Scarecrow from The Wizard of Oz. The pair spent a chunk of the year together while on tour, and they reunited for this ensemble.

Last year, Arrow star Colton Haynes dressed as Ursula from The Little Mermaid, so expectations were high. He didn’t disappoint: He was Miss Piggy to Ally Macki’s Kermit.

Star Wars: The Force Awakens star John Boyega wasn’t exactly feeling the Halloween spirit. “Perks of SW?” he tweeted. “I can call my red shorts and Michael Jordan vest a Finn after work Halloween costume.” The actor then posted video of his non-costume on social media.

Jenna Dewan Tatum was a little more festive and brought a touch of magic to the holiday as a glittery purple unicorn.
