Heidi Klum Henry Leni Johan Lou

On Saturday Heidi Klum and bodyguard/beau Martin Kristen stopped by the Grove in Los Angeles with her four children, and the group hit up the American Girl store, said hi to Santa Claus and even took a ride on the tram.

So is was Heidi doing last minute shopping with her kids? Not likely! "I start in the summer!" Klum told E's Marc Malkin. "I start everything early. I'm a planner. You have to be organized. I have lists—pages and pages of lists."

Gifts for Leni, Lou, Henry and Johan include unicycles, a globe, and Heidi added, "My little one wants every Pillow Pet and every Glow Blanket under the moon. It's crazy. Every five weeks they come out with a new one. The whole room is glowing."

And what does Heidi want? "I don't really want anything," she said. "I want my kids to make something for me. I have a whole wall that's dedicated to all the things they've made for me." Awwww! Heidi also revealed that they will be staying in Hollywood for the holidays. "My mom and dad were just here," she said. "It was so nice. So we're just going to hang at home. It's nice to be home."
