Heidi Klum carried her daughter Lou in her arms, with kids Leni, Johan, and Henry close by, for a trip to Times Square on Saturday in NYC. The star and her little ones took in a Broadway performance of Newsies, and got to hang out backstage afterward to visit with the cast. Heidi praised the performance on Twitter, and wrote, "Always love visiting Broadway! Amazing performance." The model and mother of four is back in the States after a recent stint in Europe. Heidi got silly for an appearance on the Spanish television show El Hormiguero in Madrid last month, traveled to her homeland for Germany's Next Top Model finals, and swung through France for bashes at Cannes. Now, she's back to focusing on Project Runway and even welcomed special guest judge Katie Holmes to the set for a day of shooting.
