Seal Stunned Heidi Klum With Icy Love Nest  5/30/06

Romantic Seal sealed his engagement to supermodel Heidi Klum by making love to her in a mountain-top igloo.

The Kiss From a Rose singer flew the German beauty to a snow-covered summit, which he'd decorated with rose petals and a little ice house, during a Christmas break in Whistler, British Columbia, in 2004.

Once the helicopter left the couple alone, Sean got down on bended knee and asked Klum to be his wife.

Stunned Klum recalls, "He'd spent two days building this fairytale wonderland that was the most amazing, crazy thing I've ever seen.

"He sang, got down on one knee and proposed, and then there was the igloo, which had to be christened."
