The couple marked theirwedding anniversary with a ceremony attended by their children - Leni, seven, Henry, five, Johan, four, and 19-month-old Lou - and 100 of their closest friends at Donald Trump`s Mar-a-Lago Club in Palm Beach, Florida, on 07.05.11.
The couple had originally planned to celebrate the occasion in Mexico at Seal`s beachfront home where they originally tied the knot on May 10, 2005, but recent unrest in the country due to drug violence led them to change the location with business mogul Donald coming to the rescue at the last minute.
A source told RadarOnline.com: "A week ago, Heidi contacted Donald Trump and asked if they could have the party at his Mar-a-Lago Club.
"He was happy to put out the welcome mat for them, even though he had another commitment that kept him from attending."
Speaking about their annual vows renewal, supermodel Heidi has said previously: "It`s our time - a lovely family time. It`s about remembering this moment of love we gave to each other and reinforcing it.
"It`s so special to us, something we love and something our children have gotten accustomed to. It`s like, `Hey, mom and dad love each other and they get married every year.
