It was a really tough time. It was a hard time for our entire families."David and I got through it together. No one said marriage was going to be easy."Yes, there have been bumps along the road. But we've come out stronger and happier. It's even better now than when we were first married. After all these years we can just come home and have a laugh."The couple - who are moved to the US this week with their three sons, Brooklyn, Romeo and Cruz, following David's decision to join Los Angeles Galaxy soccer team - were photographed by Steven Klein for the style bible.The couple, in what is their most revealing photo shoot to date, appear on the front cover semi-naked.

He said: "We like to lock the doors and wander around naked."David is also happy for Victoria to "wear the trousers" in their relationship and even lets her pick his outfits. He said: "When people say, 'Victoria wears the trousers', I'm happy with that."When she tells me something doesn't look good, I believe her."Victoria revealed the couple were not looking at the move as a means to"boost" brand Beckham, insisting "We're not out to be the most famous people in America".
