Victoria Beckham and her family hid away during the 'Viva Forever!' after-party.

The 38-year-old fashion designer arrived at the marquee on the banks of London's River Thames on Tuesday evening (11.12.12) with her husband David, 37, and sons Brooklyn, 13, Romeo, 10, and seven-year-old Cruz after the opening of the Spice Girls musical at Piccadilly Theatre but instead of joining the rest of her bandmates on the dancefloor Victoria and her family sat quietly in the corner.

However, Emma Bunton, 36, Mel C, 38, Geri Halliwell, 40 and Mel B, 37, didn't seem to mind their fifth member wasn't taking part in the singing and dancing to their hit singles.

A source told the Metro newspaper: ''Victoria sat on her own table away from the rest of the girls. They didn't speak the whole time she was there.

''When the DJ played some Spice Girls hits, Posh was nowhere to be seen. Geri, Emma, Mel B and Mel C all got up to dance and tried to remember the moves to 'Spice Up Your Life'. They didn't seem to care, or notice, Victoria was missing.''

The Beckhams were spotted leaving the lavish bash at midnight after mingling with close friend Tana Ramsay - wife of celebrity chef Gordon Ramsay - and fashion designer Roland Mouret.

A host of celebrities attended the party, including TV presenter Graham Norton and Jennifer Saunders - who penned the script for 'Viva Forever!' - and they were treated to a three course festive-themed feast with Ginger Spice honey ham, mulled wine jellies and porcini mushroom gratin among the delicious dishes.

Decor included three 20-foot crystal chandeliers, two five-foot high trifles and a giant Christmas tree.
