Surprise, surprise, it was costume Sunday for Heidi Klum's kids. There was no face paint, but Henry was in his favorite Spider-man costume for a trip out to Bristol Farms. Little Leni skipped the dress-up, though her matching haircut to mom's is pretty adorable in its own right. I mean, the whole group seems so normal and fun ... or as much as they can be with a mom slash supermodel slash reality TV host (etc, etc) running the show. Christian Siriano may be the biggest star to come out of this season of Project Runway, but no one compares with Heidi as the star.
