I predict that she will become a household name over the next five years as she gets more exposure and film and tv roles. According to her skimpy bio at IMDB, she was born Charity Rose Wakefield, in 1981 at Tunbridge Wells, Kent, England, no birthday given. It's hard to believe, but this make her at least 31 years old; in Sense and Sensibility she played 16 year old Marianne.
