Despite the reports, Victoria Beckham has already ruled out a comeback with Baby, Ginger, Sporty and Scary, stating: "I won't ever do it again.

"Sometimes you have to know when it is time to leave the party. Singing at the Olympics was an incredible honour. I was so proud to do it."

Posh Spice added to Vanity Fair Italy: "That was the perfect time to say, ‘That’s great, thanks to all, but enough'."
