Heidi Klum and her mom, Erna, took Leni and Lou to watch Henry's game in LA on Saturday. The ladies sat on the sidelines and chatted with friends while Henry played flag football. It was the end of an exciting week for Heidi and her family, who celebrated Lou's third birthday with a party at Disneyland. Heidi and her new boyfriend, bodyguard Martin Kirsten, posed for a Western picture at the California Adventure theme park and checked out the rides with Heidi's kids. The fun will continue since the season finale of Project Runway airs this Thursday and Heidi's favorite holiday is coming up. Heidi has displayed many Halloween costumes at her annual bash over the years, but it remains to be seen if she'll host a fete this year following her split from husband Seal.
