The British fashion designer claims her four children, Brooklyn, 16, Romeo, 13, and Cruz, 10, and Harper, four, with husband David Beckham, are always eager to give back and make a difference "however big or small that is."

Speaking at a charity luncheon for Fashion 4 Development in New York, the 41-year-old star said: "The children definitely want to do their bit too, which we're very proud of."

The former Spice Girls singer is particularly proud of Romeo for raising £6,000 for the Joint United Nations Programme on HIV/AIDS and the 7 fund, which is a collaboration with UNICEF providing assistance to children in danger zones around the world, by running a three-mile children's marathon in April.

She told E! News: "Romeo last year actually ran in the marathon and he raised money for both UNAIDS and David's charity as well that he has with UNICEF.

"As a family, we want to do whatever we can do to help and make a difference however big or small that is."

While Victoria previously insisted she and Dave try not to spoil their sons, the retired footballer recently admitted he has "no power" over their daughter.

He said: "I love all my children, of course, equally but I'm definitely stricter with the boys than I am Harper, which gets me in trouble with my wife of course."
