The 42-year-old fashion designer - who has Brooklyn, 17, Romeo, 14, Cruz, 11, and five-year-old Harper with her husband - has revealed David's secret to always looking good.
Speaking on ITV's This Morning, she said: "David does steal my beauty products! It doesn't annoy me, he looks so beautiful, that no, it doesn't annoy me."
Meanwhile, the former Spice Girl previously insisted she couldn't do her job without the support of her husband.
She said: "David [is] so great. I couldn't do any of this without him. He is very supportive and it means I can come away and work and know he is being the best dad looking after the kids. We work very well together, because David travels a lot and when he travels I am at home. There is always someone there with the children."
And Victoria recently gushed about how David is the "best partner anybody can have".
She added: "David comes to my shows and David is my business partner. Everything we do, we do everything together. We really support each other ... He's the best partner anybody can have.
"I tend not to talk too much about work when I get home because I've been working on it all day and there's so many other things to catch up with regards to the children and what he's doing."
