"It's actually been 12 years since they did the Olympics in the U.K. but over 15 years since they actually were on a stage together. So obviously having them all there that night, and I didn't expect them to all get up on stage," he said of the event. David continued: "But I had a whole video planned where me and my kids recreated the 'Mama' video. My son, who plays the guitar and sings, had a song, and he sang 'Mama,' and all of a sudden all the girls got up — and I'm their biggest fan, you know? I tend not to tell my wife that. I tend to tell her that I fancied her, but she was a Spice Girl. I love that about her... So I was a fan." On Saturday, April 20, the fashion designer marked her milestone birthday with a star-studded bash in London. David Beckham and Jimmy Kimmel on May 8, 2024.
