The couple - who have children Brooklyn, 16, Romeo, 12, Cruz, 10, and three-year-old Harper - reach the marital milestone this weekend and plan to mark the occasion with all their family and friends.

A source said: "Victoria would love to stick two fingers up to those who said she and David would never last.

"Their marriage is getting better and stronger with each year and, the older they get, the closer they become.

"They'll be in LA for their anniversary and because it falls on Independence Day, they're planning to celebrate with a big barbecue on the beach with their family and friends."

With David retiring from his soccer career, he has been spending more time at home and he and his fashion designer wife feel their relationship is stronger than ever.

The source told Closer magazine: "Victoria is still worried that David's business ventures will mean more time apart, but she's happy for now as he's home a lot.

"It's made him really mellow and Victoria feels like they have a proper partnership.

"David really admires the strong woman his wife has become and she feels their bond is unbreakable."
