The superstar couple is said to have asked singer-turned-snapper Adams to help them mark the milestone date by shooting a series of pictures of them with their sons Brooklyn, Romeo and Cruz.

They'll then reveal the photos at a celebration of their big day on 4 July (09), according to Britain's News of the World newspaper.

A source tells the tabloid, "They're going to pose for some romantic photos, and then have a big family photo with their three boys.

"The Beckhams want to unveil the photos in front of everyone on their big night on July 4."
