Heidi Klum feed kids raw fish?

Heidi Klum wants to feed her children raw fish on holiday.

The German-born supermodel who raises daughters Leni, seven, and Lou, 20 months, and sons Henry, give, and Johan, four, with husband Seal is planning a trip to Italy with her brood and is most excited about an unusual adventure on the seas.

“What’s next? To go on a great holiday with my family. We’re going on a boat to Italy. I love when the kids can go and eat sea urchin and the sea urchin is literally going like this [waves hands],” she said.

“You cut the bottom off and then you eat it.

“That’s what they do when you go to [restaurant] Nobu or whatever it’s the same sea urchin, so you might as well eat it when it first comes out of the sea.”

The 38-year-old beauty’s break comes before she starts working on the ninth series of TV show Project Runway, and despite her long stint on the program, Heidi revealed her husband has never watched an episode.

“You know, my husband has never seen one episode. What about that for a fun fact?” she said.

“He’s come to the set, but he hasn’t watched an episode.”
