Celebrities kicked off New York Fashion Week last night by strutting their stuff forThe Heart Truth’s Red Dress Collection 10th anniversary fashion show. Rebecca Romijn, Christie Brinkley, Chaka Khan and Minka Kelly were just a few of the famous faces who took turns down the runway in ruby designer dresses, helping to raise awareness about women’s heart disease. “This is so nerve-racking,” Kelly told InStyle.com before show, which was hosted by Diet Coke, Bobbi Brown, and Elizabeth Arden Red Door Spas. “I’m just focusing on not falling down. I’m going to think of Tyra Banks!” And she didn’t stumble one bit—rather, she flaunted her sequin-covered Diane Von Furstenberg gown fabulously, an accomplishment front-rowers (and Ty’s America’s Next Top Model besties) Jay Manuel and J. Alexander looked so proud of. See all of the celebrities who hit the runway in the gallery!
