London, Nov 16 : The posh hooker, whose notorious Belle de Jour blog was adapted into the TV hit ‘Secret Diary Of A Call Girl’, has revealed her identity—she’s a research scientist.

Dr Brooke Magnanti''s explicit Internet story of her experiences as a call girl was first turned into a book and then inspired the ITV series with Billie Piper in the lead.

She worked as a 300 pound-an-hour prostitute while writing her thesis as a student between 2003 and 2004.

Magnanti, 34, works for the Bristol Initiative for Research of Child Health and has now revealed her identity because she feared an ex-boyfriend might expose her.

"I don''t want this massive secret over me any more. I stand behind every word with pride,” The Sun quoted her as saying.

And she said the work was "so much more enjoyable" than the shifts she did by day as a computer programmer.

Magnanti admitted that some sex workers have bad experiences but she was lucky.

Her bosses at Bristol University said: "Her past is not relevant to her current role." (ANI)
