Victoria Beckham was apparently on a high after the premiere of Spice Girls musical Viva Forever, singing and dancing at the after party.
The fashion designer - who held up the show by arriving late and sat separately from the rest of the band, joining her family instead - couldn't resist a little nostalgia as she was spotted singing Spice Girls tunes in the loo at the lavish banquet in London's Victoria Embankment Gardens.
A party insider revealed: "Victoria arrived at the party before the rest of the girls with husband David Beckham and her three sons Brooklyn, Romeo and Cruz.
"She took Cruz to the loo and was dancing outside the cubicle telling him to hurry up because she wanted to go and started singing the words to Wannabe, 'I really, really, really wanna...' She was giggling with her friends and sister Joanne and then broke into a rendition of Spice Girls hit Stop."
Geri Haliwell, Mel C, Mel B and Emma Bunton all arrived in a taxi together and partied the night away, taking to the dance floor together to show off their moves.
Guests at the party were treated to an incredible Christmas themed banquet, with tables piled high and decorated with toys, chocolate shoes and giant trifles.
