The couple, who have made a loving habit out of renewing their vows on their anniversary each year, was married May 10, 2005 at Seal's beachfront home in Mexico.

"A week ago, Heidi contacted Donald Trump and asked if they could have the party of his Mar-a-Lago Club in Palm Beach," an insider tells RadarOnline.com exclusively.
He was happy to put out the welcome mat for them, even though he had another commitment that kept him from attending."
