The former singer - who has sons Brooklyn, 10, Rome0, seven, and four-year-old Cruz with soccer star husband David Beckham - was delighted to get the chance to share a stage with Geri Halliwell, Emma Buton, Mel B and Mel C again in 2008.
She told Heat magazine: "It was such a big opportunity to celebrate the past and thank our fans.
"The boys were the main reason for doing it - so the could see what I used to do. Normally it's all about David, but the boys were really proud."
Despite reuniting for the tour, Victoria - who is now a successful fashion designer - was the only Spice Girl not to partake in a solo song, instead choosing to parody herself as a model.
Rumours have been circulating that there could be a second reunion of the girl band.
Speaking in a television interview earlier this year, Geri said: "Right now, we are gathering information and thinking about possibilities."
Reports have suggested that the group will also come together to cast actresses to play them in a Spice Girls musical.
