Nicole Kidman, Milo Ventimiglia, Alexander Skarsgard, James Franco, Millie Bobby Brown, Claire Foy, Kerri Russell, and more all joined in on the fun, singing and reading out the lyrics with their own unique styles.
Kidman went for a more seductive approach while Brown was all about the Sporty Spice high-energy action.
The clip was quickly noticed by Posh Spice herself, Victoria Beckham, who posted the video to her own Instagram account, writing, “Happy 21st anniversary #wannabe!!! Love this, thank you @wmag! x VB #girlpower @officialmelb @melaniecmusic@emmaleebunton @therealgerihalliwell.”
Some of the A-listers were then asked who their favorite Spice Girl was, and Kidman was Team Posh.
“It would have to be Posh, right?” Kidman said, opening up about Beckham’s current career as a fashion designer. “[She’s] really good, I wore one of her dresses recently and I was like, ‘Oh, this is heaven.”
