Red-hot celebrities Ashanti, Joss Stone and Molly Sims donned sexy, sassy crimson-colored dresses at yesterday’s “The Heart Truth’s Red Dress Collection,” a show to raise awareness about heart disease. First Lady Laura Bush – in a questionable white suit, red lips combo – opened the morning’s festivities with a short speech. “Nothing draws attention like a little red dress,” she said.

The supermodels and superstars – Heidi Klum in Marc Jacobs, singer Joss Stone in Max Azria Atelier and “24”s Mary Lynn Rajskub in Monique Lhuillier – helped spread the word.

“Dancing with the Stars” Lisa Rinna, in Michael Kors, showed of her best moves as she wiggled down the runway, stopping at the end for a quick sultry shimmy directed towards actor-husband Harry Hamlin.

Other dancing divas included Rita Moreno who did a little salsa in her tight Lily Samii and Ashanti who shook her money-maker in a tight Tracy Reese. Liza Minnelli, in Halston velvet beaded pants and a beaded twin set, lent her voice to the cause, belting out “New York”, even though she did flub the lines.
