Scarlett Johansson has ditched her signature platinum locks, and dyed her hair brunette. Appearing at a photo call for new movie The Spirit, the newly-wed showed off her latest look, and seemed to have had a style makeover as well. Always one for a figure-hugging frock, the actress instead donned an understated baggy jacket, black trousers and some classic courts. Instantly sparking rumours that she might be pregnant, her rep quickly put an end to speculation telling E! News, ‘She is not pregnant.’
