Former prostitute Belle de Jour drops her anonymity
A research scientist revealed herself as the former call girl who writes under the pseudonym Belle de Jour.
Dr Brooke Magnanti, who is working for the Bristol Initiative for Research of Child Health, said the "massive secret" was making her paranoid and affecting her behaviour.
Interest in the author's true identity increased when her memoirs were turned into the television series Secret Diary Of A Call Girl, starring Billie Piper.
Dr Magnanti, 34, who lives in Bristol, said she decided to unmask herself because she feared an ex-boyfriend might reveal Belle's true identity.
