Gold medal moment!

The Spice Girls were the pop music victors at Sunday night's Closing Ceremonies spectacle for the London Olympics, with the five-member girl group stealing the spotlight with a much-anticipated, over-the-top reunion performance that didn't disappoint.

And even Victoria "Posh Spice" Beckham -- not known for being particularly effusive -- was bowled over by the big moment.
