Celebrities strut their stuff for a good cause at The Heart Truth's annual Red Dress fashion show during fashion week, and this year's line-up includes Kristen Chenoweth (who walked the show in 2007), Kim Kardashian, Dania Ramirez, Jordin Sparks, Estelle, Jewel, Rose McGowan, Mamie Gummer and Felicity Huffman. Featuring red dresses created by some of the hottest American designers, the show helps raise awareness for heart disease and also raises money by auctioning off many of the dresses with Clothes Off Our Back. Stay tuned for our coverage of the show on February 11th.
