David Beckham is ''proud'' of wife Victoria for becoming a credible fashion designer.

The soccer star - who has four children, Brooklyn, 13, Romeo, nine, seven-year-old Cruz and 11-month-old Harper with his spouse - knows it was ''hard'' for her to establish her career away from her background as a singer in the Spice Girls.

He said: ''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 attended Victoria's New York Fashion Week presentation in February, and though he enjoyed his first fashion show, he admitted he stayed quiet while he was there because he was surrounded by knowledgable people in the industry.

He told Elle magazine: ''I'm really surprised by how short the shows are. All the work that goes into them and it's done in minutes. But it was the best five minutes I've had in a long time.

''I was sat next to a few fashion people and I felt like I had to keep my mouth shut. But I knew certain things. I knew, 'Great lines and great shapes' and 'There were a couple of great colour pops'. So, you know, I knew certain things.''
