Back in July 1999, Posh and Becks, after two years together, wed at Luttrellstown Castle in Ireland.
The couple had welcomed son Brooklyn just four months before and he acted as the adorable ring bearer.
Bride Victoria wore a traditional Vera Wang gown for the ceremony but then she and David changed into their iconic matching purple outfits.
Though the couple have faced their fair share of scandals, the Beckhams have built the ultimate celebrity legacy.
After Brooklyn came along in March 1999, Posh and Becks welcomed Romeo in September 2002, Cruz in February 2005 and Harper Seven in July 2011.

In 2018, David made a rare comment about his and Victoria's marriage and said it's "always about hard work".
"You know your children, they want your time and they deserve your time, and we are hard working and we feel that is the right way to bring up our children. To prove and to show them that actually, you have to work really hard to be successful," he told Lisa Wilkinson.
"To have been married for the amount that we have, it's always hard work, everybody knows that. But you make it work," he added.
