Heidi Klum, Kim Kardashian, Estelle, Bethenny Frankel (left), Raven Symone, Kristin Chenoweth, Jordin Sparks, Felicity Huffman and Kimora Lee were among the stars who donned red gowns in and sashayed down (what else?) a red carpet in support of the Heart Truth campaign, which is an organization devoted to raising awareness of heart disease as the leading cause of death for women.

The celebrity models certainly had plenty of heart, and all looked stunning in their shimmery red dresses, by designers from Marchesa to Oscar de la Renta. With few exceptions, these women are curvy--and proud of it. Not least of them, New York's pregnant "Real Housewife"! No word on whether Bethenny talked baby tips with "Desperate Housewife" Felicity Huffman, whose television character is also expecting a baby any week now.
