In the nine years since they last took to the stage together, the Spice Girls have done a lot of growing up.
So too, it must be hoped, have their fans. Because Saturday's opening night of the group's British tour saw them perform a particularly raunchy set.
Victoria shows unexpected flesh in wrong places
Singing, dancing and gyrating in front of 20,000 cheering fans, they caused quite a stir at the O2 arena in London.
Their costumes, by Italian designer Roberto Cavalli, were equally memorable, displaying varying amounts of flesh. They changed eight times during the two-hour show.
Baby Spice Emma Bunton, who injured her ankle last week, wore an ankle brace but had to leave the more energetic dance moves to her bandmates.
Celebrity guests in the audience included R&B singer Rihanna, chef Gordon Ramsay and Victoria Beckham's husband David and their sons Brooklyn, Romeo and Cruz.

Yet when the girls took to the stage for the first time in almost a decade, Victoria Beckham showed a little more flesh than expected – and in all the wrong places.
The 33-year-old suffered a "wardrobe malfunction", spilling out of her tight golden corset and exposing an unattractive lump of flesh just under her right armpit.
Rumour had it that Posh had her breast implants taken out before the world tour, fearing they would pop out of her Roberto Cavalli outfits during energetic dance routines.
