The Spice Girls Reunite As a Threesome

Get ready, everyone: Mel B, Emma Bunton, and Geri Halliwell are reuniting for the 20th anniversary of the Spice Girls' single "Wannabe," and made it official via social media yesterday.

The details are still few, but so far we know that this reunion will not include Mel C, or Victoria Beckham (who probably has a case of the Mary-Kate-and-Ashley-Olsens, since she's obviously way too "chic" now to give props to her origins).

Going as GEM, the trio announced the news, sort of, in a fun but somewhat cryptic YouTube video in which they invite all their loyal fans (in other words, us) to a party. What kind of a party, you may ask? And does it involve a new album and a major world stadium tour???

Watch here and speculate along with the rest of us:
