The Spice Girls had us reliving the '90s (and contemplating stripy highlights) as they celebrated "Wannabe" turning 25 on Thursday with some seriously throwback pics.

Geri Halliwell, a.k.a. Ginger Spice, a.k.a. Sexy Spice, posted a series of photos celebrating the moment, with the first image showing the girls together — including Victoria "Posh Spice" Beckham (nee Adams) smiling (no, really!) — in her old backyard.
