Stars including singer Toni Braxton, "Fashion Police" host Kelly Osbourne, and actress Brenda Strong (above) strutted their stuff modeling the Heart Truth's Red Dress Collection at Mercedes-Benz Fashion Week on Wednesday.

The Heart Truth campaign raises awareness about heart disease in women, and ladies such as actress Minka Kelly, Olympic gymnast Gabby Douglas and fitness guru Jillian Michaels wore crimson to show their support for the cause.

Reality stars Kylie, Kendall and Kris Jenner also made their way down the catwalk in slinky red dresses.
