Knightley, who lives in London, is involved with her Pride and Prejudice co-star Rupert Friend. Knightley has stated she has no plans to be married in the near future. She previously dated Northern Irish fashion model Jamie Dornan, as well as actor Del Synnott, who, according to some reports, attempted suicide after their relationship ended, although Synnott and Knightley deny these claims.
Knightley has denied rumours she is anorexic, although she did say—after her appearance at the Pirates of the Caribbean: Dead Man's Chest premiere led to media speculation that her extremely slender figure was due to an eating disorder—that her family has a history of anorexia. Knightley sued the Daily Mail after they claimed she lied about having anorexia; the article said that a teenage girl died from anorexia, indicating that Knightley's physical appearance may have influenced her in some way. She was awarded a settlement for it. In July 2006, Knightley said she has become a workaholic, detailing that "the last five years have blended into one. I can't tell you what was last year and what was the year before" and specifying that she was "working too much" and was "quite frightened that if I continue at this rate I will start to hate what I love," even suggesting that she would take a one-year break from acting to travel and focus on her personal life.
