Heidi Klum: Family Day at the Museum

Posted Saturday December 29, 2012 10:26 AM GMT

Rounding up the kids for a fun Friday, Heidi Klum and Martin Kristen took her children and her mother to Pretend City Children's Museum in Irvine, California, followed by lunch at a nearby restaurant (December 28).

The "Project Runway" host was dressed casually in a black zip-up sweatshirt, torn jeans, and black high-tops as she carried little Lou on her hip while her beau held hands with Johan.

Earlier that morning, the 39-year-old model was spotted in a black and gray patterned tracksuit as she and Martin took Lou to Starbucks for a morning fuel-up.

Making the most of her time off, on Thursday the happy family was seen on a bike ride in Santa Monica.
