Victoria Beckham's Spice-y hair

Victoria Beckham has returned to her classic brunette bob for the Spice Girls' upcoming world tour.Victoria decided to ditch her blonde locks and spent eight hours having her hair dyed dark brown at Los Angeles' Jessica Galvin Hair Studio on Friday (26.10.07).She is now sporting the same hairstyle she had when the Spice Girls first found fame with 'Wannabe' in 1996.The 33-year-old singer, who is married to soccer star David Beckham, was eager to keep her new locks a secret and rushed out of the hairdressers wearing a cap.A source said: "The girls have changed since their heyday but Victoria wants her fans to remember how she used to look. Her dark bob made her the person she was and she wanted to turn back the clock. She is sure the fans and the other girls will love it."Earlier this month, Victoria revealed she was ready to change her hair colour, saying: "My hair just feels so luminous at the moment. I had this blonde colour done in Los Angeles when it was really bright and sunny."Now I go back to the UK and it's a bit overcast and cold and I feel like I'm glowing in the dark. It's time for a change and let's just say it'll be quite different."

The reunited girl group - Victoria, Mel B, Emma Bunton, Geri Halliwell and Mel C - are set to kick-off their world tour in Vancouver, Canada, on December 2.
