Va-va voom!

Hollywood's hottest stars really let themselves hang out for this year's red carpet at the Screen Actors Guild Awards. The daring looks are a stark contrast from the Golden Globe Awards two weeks ago, where the gowns highlighted actresses' sexy backs.

Sofia Vergara showed off her curves in a low-cut royal blue Roberto Cavalli dress.

"I was a little worried because it was sexy," Vergara told E!'s Giuliana Rancic on the red carpet. "But the SAGs are fun, and I love the color."

Her Modern Family costar Julie Bowen wore a sleek Catherine Malandrino pantsuit with a plunging neckline (and low-back, too!).

Glee star Lea Michele's Oscar de la Renta gown had a wide and low v-neck, while Eva Longoria's Georges Hobeika gown showed off her decollete.
