"I won't do it ever again," the singer-turned-fashion designer confessed as she posed for Vanity Fair Italy and Spain. "Doing the Olympics was an incredible honour. I was so proud to do it; proud to be British…
"That was the 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."
Since the Spice Girls officially disbanded in 2000, Victoria has gone on to become a hugely successful fashion designer, whose dresses have been worn by A-listers including Julia Roberts, Beyone, Kate Winslet, Cameron Diaz and Blake Lively.
That's not to say she doesn't see a connection between her new career and her days as a pop star.
"The Spice Girls were successful because we celebrated women. That's why I do what I do today."
The mum-of-four also spoke about the moment she was awarded a BAMBI trophy in Berlin last year by fashion icon Karl Lagerfeld.
"His words when he gave me the award meant so much… The fact that he has anything to say about me, I'm constantly pinching myself!"
