Ed Sheeran revealed just how big of a Spice Girls fan he is when he busted out an impromptu duet with Baby Spice herself! Emma Bunton invited the pop star on her Heart radio show, where the two performed Spice Girls' "Goodbye" single from their third and final album, Forever.

Sheeran, Bunton and Sheeran's trusty acoustic guitar sounded great together, and the fangirl moment following the duet was even cuter. The Divide singer joked about being "the next Ginger Spice" and requested the iconic Union Jack dress to make it official.
