Spice Girls reunion: Watch girl group perform 'Stop' at Victoria Beckham's 50th birthday party

Victoria Beckham is spicing up her 50th birthday.

All five of the Spice Girls reunited at Beckham's 50th birthday party, as seen in a video shared Saturday on Instagram by David Beckham. He filmed his wife and her former bandmates — Melanie C, Mel B, Emma Bunton and Geri Halliwell — dancing to the girl group's song "Stop."

"I mean come on," the former soccer star wrote.

Victoria Beckham, who was known as Posh Spice when she performed with the Spice Girls, also shared a video of the moment on her Instagram account, writing, "Best night ever! Happy Birthday to me! I love you all so much!"

"The best gift to be reunited!! Thank you to all my friends and family for celebrating with me," Victoria Beckham later tweeted Monday, sharing a set of photos of her posing with the other Spice Girls, Eva Longoria, her husband and Tom Cruise, and her daughter, Harper Beckham.

Emma Bunton, also known as Baby Spice, shouted out David Beckham for organizing "such a wonderful evening" on X, formerly Twitter. "What a night," she wrote Monday. "Love all my girls."

The surprise performance comes 30 years after the formation of the Spice Girls in 1994, as well as five years after the group kicked off a 2019 reunion tour. But Beckham didn't participate in that tour, explaining on "Good Morning America" at the time that she "wouldn't be able to" join because she was too busy with her design work.

Still, Beckham told "GMA," "I'll always be a Spice Girl, and I'm so proud of everything I achieved. I'm proud of them. It's going to be the best show." She added, "In spirit, I will absolutely be there."

In September, though, Mel B suggested to "Extra" that Beckham is now "on board" with a reunion without specifying what form this might take. And last month, when asked about the Spice Girls coming back, Mel B teased on "Loose Women" that "we are definitely doing something," but again did not get into specifics.

"Us five are working on something that is going to be announced soon," she cryptically declared on the "Today" show.

Video of the reunion at Beckham's birthday party quickly racked up more than a million likes, as fans celebrated seeing the group back together again.

"The moment the entire planet has been waiting for," one comment read, while another fan wrote, "The way a whole generation is SHAKING."
