It’s a Spice Girls reunion!

At her 50th birthday party on April 20, Victoria Beckham rejoined her former bandmates Geri Halliwell-Turner, Emma Bunton, Melanie “Mel C” Chisholm, Melanie “Mel B” Brown to perform the dance routine to their 1997 single “Stop” in front of thrilled party guests.

The special moment was caught on video by Victoria’s husband David Beckham, and posted by the pair on their Instagram accounts the morning after the bash, which was held at private members’ club Oswald’s in London.

“Best night ever! Happy Birthday to me! I love you all so much! #SpiceUpYourLife,” Victoria wrote in her caption.

“I mean come on x @victoriabeckham @melaniecmusic @officialmelb @emmaleebunton @gerihalliwellhorner 💚💛🧡💜💙🩵🩷🤍,” David captioned his post of the same video.

In the clip, David first filmed his excited expression as he stood in front of Halliwell, 51, Bunton, 48, Mel C, 50, Victoria and Mel B, 48, dancing in a row onstage to “Stop” — in exactly the same positions as in the music video — as the song played on loudspeakers at the party.

As the chorus rang around, the ladies raised their arms and flashed stop signs with their hands as they carried out the group’s iconic dance routine for the song.

At one point in the video, David mouthed the words to the track along with them, before he whipped the camera around to film himself briefly as he enjoyed the performance. Party guests Eva Longoria and Marc Anthony also appeared to ve dancing in the background of the video during the performance.

The Spice Girls’ party performance comes after the group celebrated their 30th anniversary since first auditioning for the band last month, and the former member and fashion designer made an expectedly chic appearance at her birthday celebrations in a sheer mint green gown, as she walked on crutches, following the foot injury she suffered earlier this year.

The Beckham family also attended the bash as Victoria and David’s children: daughter Harper, 12, and three sons Brooklyn, 25, Romeo, 21, and Cruz, 19, were pictured arriving in their formal outfits for the landmark occasion.

Ahead of her birthday celebrations, Victoria posted photos of her posing with David and their kids in their party looks on Instagram as she wrote, “Can’t wait to celebrate with my friends and family! I love you all so much,” tagging her family.
