The 21-year-old supermodel dished on her most recent invitation to the "Shake It Off" singer's house when she appeared on Today Wednesday. "Halloween was really cool. We were all working, so my friend had just a little girl's night at her house," Hadid explained.
Of course, that friend is the 26-year-old Grammy winner who hosted Hadid, Camila Cabello, Martha Hunt, Lily Donaldson and more famous faces. What do a bevy of Hollywood's young and fabulous snack on when they're all together?
"We had like chips and guacamole and pizza," Hadid said. The perfect girls night, indeed.
While the Maybelline model showed up to the party dressed like a cub scout, the getup wasn't her original idea.
"I had a really, really intense costume planned and then I was like maybe I'll save it. So, then I found a cub scout shirt in Japan at a vintage store and I made a costume out of it," she recalled.
"I'm sure your Instagram followers, 25 million, will love that picture," NBC's Matt Lauer pointed out.
He was right—one photo of Hadid in her costume has accumulated 1.3 million likes...so far.
