Victoria Beckham won't perform with the Spice Girls ever again.

The 39-year-old fashion designer admits it was an "incredible honor" to sing with Geri Halliwell, Emma Bunton, Mel B and Mel C at the London Olympics closing ceremony in 2012, but thinks it was the perfect time for the group - who separated in 2000 and undertook a reunion tour in 2008 - to call it a day for good.

"I won't ever do it again. Doing the Olympics was an incredible honor. I was so proud to do it; proud to be British... That was a perfect time to say, 'That's great. Thank you to everybody, but no more.' Sometimes you've got to know when it's time to leave the party," she said.

While Victoria is now a successful fashion designer, she thinks her previous pop career helped her in her current work. Speaking to Spain and Italy's Vanity Fair magazines, she said, "The Spice Girls were successful because we celebrated women. That's why I do what I do today."
