Get in your time machine and go back to 1997 -- the sold out Spice Girls reunion performance at the Staples Center brought the house down!

The crowd went wild as Posh, Geri, Mel. B, Mel. C and Emma performed classics like "Spice Up Your Life" and "Two Become One" and also showcased their solo Posh's solo where she walks down the stage as if it were a runway and, uh, messes up her hair! Yeah, that was like, so awesome!
