SEAL & HEIDI

When it came to asking for his sweetheart's hand in marriage, British singer Seal, 42, spared no expense, proposing to model Heidi Klum, 31, at 14,000 feet in Whistler, B.C., on a glacier "in an igloo built just for the moment," he explains. The couple, who began dating last year, are already a family: Seal calls Klum's 11-month-old Leni (with ex Flavio Briatore) "my daughter" and they're expecting their first baby together in the fall.
