Washington, Nov 20 : British soul singer Seal has spilled the beans on how he and wife Heidi Klum manage to keep the romance alive in their four year long marriage.

Among the many special gestures that the supermodel does for her husband, Klum often puts ‘beautiful notes’ in the singer’s luggage whenever he has to move out.

"She packs for me with beautiful notes in my luggage that I discover. She''s always doing sweet things,” People quoted him, as saying.

Even Seal leaves no soul unturned to keep his wife happy. He jetted off to Miami to lend support to Klum, as she showed off her svelte figure at the Victoria Secret Fashion Show this past weekend.

"I''m supposed to be working," says the singer, who was promoting his new album Soul, a collection of classic soul songs, in New York City last week.

"But I managed to move things around so I headed to Miami. We try and do a date night once a week. And we have vacations where we leave the kids with grandma and grandpa and go off and do our thing," he added.

Seal also revealed that his kids Leni, 4, Henry, 3, and Johan, who turns 2 on Nov. 22, are his toughest critics.

“They make it known what they like and they''re pretty good litmus test," he added. (ANI)
