The 37-year-old says he knows how much Victoria has struggled to establish her career away from her background as a singer in the Spice Girl, reported Femalefirst.
"I'm so proud. When you prove people wrong it's really satisfying and I think she's done that. To go from a Spice Girl, a pop star in the biggest girl band in the world, to a respected fashion designer, that's a hell of a step. Even I know that's a hard thing to do. She's done unbelievably well," David said.
The soccer star has four children, Brooklyn, 13, Romeo, nine, seven-year-old Cruz and 11-month-old Harper with Victoria.
