The 34-year-old actress, who is a panel judge at this year's event, wowed the crowds in an Elie Saab 50's inspired frock.

The fabulous dress featured a tulle skirt and gorgeous beaded embellishment at the bodice.

Casta paired the pretty dress with a pair of pointed stilettos that rocked the outfit up a bit.

She wore her hair down in loose waves, while a slick of red lipstick and some copper eyeshadow finished off the look perfectly.
