On Saturday morning Heidi Klum got coffee with beau Martin Kristen and her two youngest children, Lou and Johan. Maybe the former Victoria's Secret beauty was still worn out after shooting all day on Friday?

Heidi filmed scenes for her reality show Germany's Next Top Model in Venice yesterday, and not only was there a lot to cover, but Heidi had quite a few outfit changes. Of course, she was in good spirits the whole time, but that's gotta be a lotta work!
