Celebs were seeing (and wearing!) red last night in NYC -- where a group of gorgeous gals walked the runway in crimson clothes for a good cause.

Dita Von Teese, Audrina Patridge, Natasha Bedingfield, Ann Curry, Denise Richards, Cat Deely, Guiliana Rancic, Gayle King, Julianne Hough, Suanne Somers, Dania Ramirez, Patti LaBelle, Taraji P. Henson and "30 Rock" star Katrina Bowden all hit the catwalk in red for the Heart Truth Fall 2011 Fashion Show as part of Mercedes-Benz Fashion Week last night.

Camilla Alves and Eva Amurri walked the show as well and had celebrity cheerleaders in the audience -- Camilla's husband, Matthew McConaughey, and Eva's mother, Susan Sarandon, were both spotted at the show.

The annual Heart Truth show is part of a campaign to "encourage women to protect their heart health and take action to lower their risk for heart disease."
