Heidi Klum Leni Johan Lou Henry Heidi Klum Leni Johan Lou Henry

Heidi Klum hung out with daughters Leni and Lou in New York City on Saturday, and the ladies did so much shopping, it looks like little Lou was completely worn out by the end of the day!

Heidi and her girls were also joined by her mom Erna (sidebar: she looks more like the 39-year-old supermodel's older sister!) and later on we spotted the former Victoria's Secret Angel with her sons as well.

And family isn't the only thing on her mind these days ... can you believe Heidi is gearing up to promote the 10th season of Project Runway? The show premieres next Friday on Lifetime ... will you watch?
