"Halloween was really cool," the supermodel, 21, told Matt Lauer. "We were all working, so my friend had just a little girls' night at her house."
That friend, of course, is the "Shake It Off" singer, 26, who gave fans a sneak peek inside her exclusive party on Instagram on Halloween night. Fifth Harmony singer Camila Cabello and models Lily Donaldson, Martha Hunt, Emmie Gundler and Kennedy Rayé were also in attendance.
"We had, like, chips and guacamole and pizza," Hadid explained.
Inside the soirée, the bevy of beauties rocked both sexy and hilarious costumes, including a space cadet (Donaldson) and a grandmother who lost her cat Meredith (Cabello). Hadid arrived in an adorable cub scout costume, but she said that wasn't her first choice.
"I had a really, really intense costume planned, and then I was like, maybe I'll save it," she explained on Today, where she was promoting her new Stuart Weitzman shoe line. "So then I found a cub scout shirt in Japan at a vintage store, and I made a costume out of it."
"Thanks @vancityreynolds for this costume," the singer later captioned an Instagram photo of herself wearing the red superhero costume alongside Hadid. "You're the BEST deadpool inside contact ever."
