Seal and Heidi Klum sing duets together.

The singer and his supermodel wife - who had their first baby together earlier this year - love nothing more than warbling in the privacy of their own home.

The beautiful blonde revealed: "We sing all the time, just no one hears it. It's probably better that way."

Meanwhile, Seal loves changing dirty nappies.

The star, who is dad to baby Henry, is a dab hand at clearing up baby poop, according to Heidi.

When asked who changes smelly nappies in her household, the catwalk beauty revealed to Britain's Night and Day magazine: "Sometimes Seal is better at it than I am."

The sexy blonde also sung Seal's praises saying he is the perfect father.

She added: "I have a lot of help, I have a great mom and a great husband.

"I'm very much the Speedy Gonzalez - I do a thousand things. When we go, I pack the bags in 10 minutes - I have this bottle, that bottle, diapers."

"Seal is still talking to Henry. It takes longer for him, but I love that - he really takes his time."
