Gwyneth PaltrowActress Gwyneth Paltrow isn't known for her daring red carpet style, but on Tuesday night at the premiere of her new film 'Country Strong,' she wore a floor-length white dress by Emilio Pucci that elicited wows from the crowd.

The front of the dress appeared to be simple, covering Paltrow's shapely figure entirely. But once she turned to show off the back, people realized it was backless and slashed down across her left hip.
