The singer will take to the stage with her four bandmates - Geri Halliwell, Mel C, Emma Bunton and Mel B - in Vancouver, Canada, as the girls kick-off their hotly anticipated world tour.
But soccer star David will not be there to lend his support as she doesn't want the added pressure of knowing he's in the audience.
David - who has three sons, Brooklyn, eight, Romeo, five, and two-year-old Cruz, with Victoria - said: "One minute Victoria is saying she wants me there and then it's, 'No, don't come to the first show, as we'll all be too nervous.'
"But I think I'll be at the show a couple of days later in San Jose and have the boys with me. And I know Victoria will ring me as soon as the first show ends.
"She says the rehearsals have gone amazingly well."
