Rosie Huntington-Whiteley looked devastatingly beautiful (without much effort) on the red carpet at the 15th Annual Hollywood Film Awards Gala which was held at The Beverly Hilton Hotel, California last night.

She opted for a long-sleeve Emilio Pucci Fall 2011 dress.

Her ornate embroidered floral dress, which is elegantly offset by the crystal embellishment, has an open back and a subtle side split for added sex appeal.

With the rich mix of colours, Rosie kept her hair and makeup very simple.

Beauty-wise she opted for a slightly messy bun and a neutral lip colour.

Christian Louboutin Pigalle pumps completed her look.
