Victoria Beckham has been struck down with a chest infection, putting the Spice Girls' world tour in jeopardy.
The 33-year-old singer is worried she will not be fit enough to join the other girls for rehearsals in a few weeks time ahead of their performance at the Victoria's Secret Fashion Show at Hollywood's Kodak Theatre, which will be aired on November 15.
The actual tour kicks off on December 2, in Vancouver, Canada.
A source said: " Victoria can't get rid of her infection. She has been fighting it for two months.
"She's worried she won't be fit while all the other girls are turning their bodies into machines."
Victoria - who is due to fly to London with her fellow Los Angeles-based bandmate Mel B today (19.10.07) to shoot the group's video for new single 'Headlines' - admitted she has already been forced to miss a couple of rehearsals.
She said: "All the others have done a few sessions but I haven't had a chance. ( FF )
