It’s that time again – Seal and his wife Heidi Klum are already busy planning their annual May anniversary party, which always includes a fresh renewal of their wedding vows.

The “Project Runway” host and the singer were married in May 2005 and have four children together.

Last May, the couple celebrated their fourth anniversary with a “white trash” themed wedding party. [View photo below.] This year, the supermodel is going a different route.

“It’s going to be all brides and all grooms,” Klum revealed to People. “All of the women will be brides and all of the men will be grooms. …I like to have fun and I like to make it fun for my family and friends.”
