Fans were thrilled to see the fashion icon and pop star reunited with the Spice Girls, and took to the comments to revel in the birthday celebration.

“I wish I was a fly on the wall!!!” one excited Instagram user said.

“My favorite group of all time!! This is soooo iconic [flame emojis] don’t know what this does to us die hard #spicegirls fans!!”

And another replied: “The ultra-iconic picture we have all been waiting for… long live Ginger, Sporty, Posh, Baby, and Scary!”
