Madonna is set to renew her wedding vows with movie director hubby, Guy Ritchie, in a Summer 2008 ceremony at the couple’s Wiltshire, England home.

“Renewing their vows is the one way Guy and Madonna can show the world they are strong,” a spy reveals to NOTW.

“They’ve worked hard to iron out their differences to get through the tough times. It’s going to be a very emotional day and that’s why they want the people who are closest to them to share it with them.”

“They know a strong marriage takes constant effort and that they’re in it for the long haul.”
