Spice Girls Bust Some Moves in Spontaneous Reunion at Posh's 50th

If you're a Spice Girls fan, you'll want to "stop right now" and watch this video of the iconic 1990s pop stars reunited at Victoria Beckham's 50th birthday party in London.

The pop stars recreated the original choreography of their song "Stop" while appearing to sing along with the Motown-inspired hit in an Instagram video posted by Spice Girl hubby David Beckham.

The Spice Girls, which were formed in 1994, began splintering in 1998 when Geri Halliwell — Ginger Spice — left the group. The remaining four continued performing together until 2000 and have sporadically reunited throughout the last two decades.

Beckham's Saturday evening birthday party is the first time all five women have been filmed singing and dancing together since their appearance at the 2012 London Olympics closing ceremony. Halliwell, Mel B, Mel C and Emma Bunton reunited for a 2019 concert tour but Beckham declined to participate.

In January, Mel B — Scary Spice — teased another, more formalized Spice Girls reunion.

"I've been saying this forever, but now we're actually going to be releasing some really good news in about a few weeks that involves all five of us," she told Hoda Kotb, during an appearance on the Today Show.

She added: "It's going to be the gift that keeps on giving, without saying too much about it. I'm going to get myself into so much trouble."
