Heidi Klum & Her Sunday Shoppers

Heidi Klum and all four of her children - Leni, 6 next month, Henry, 4 1/2, Johan, 3, and Lou, 6 months - were spotted having lunch at La Piazza and then shopping around at the Grove in Los Angeles, Calif. on Sunday (April 18).

Heidi and the kids were accompanied by family, the nannies, and security. What an entourage!

The German supermodel - who has been married to the kids' father Seal for five years - recently told Cosmopolitan that their sex life is "nice and spicy."

I'm not big on costumes in bed, to be honest. I wouldn't say no if he wanted to try, but it seems so inorganic. Maybe it'll come later - in five or 10 years, I'll start buying funny outfits. But for now, we're nice and spicy in that department."
