Washington (ANI): Legendary actress Dame Helen Mirren will not be revealing all her secrets, or 'dishing the dirt" on people in the movie biz in her forthcoming memoirs. The Queen actress has been working on her autobiographical book named 'In The Frame: My Life In Words And Pictures". The actress has admitted that she has made up her mind to keep the focus of the book on her on-screen achievements and not on off screen secrets. "It's a celebration of my career. I'm sure it's very honest, but there is no dirt-dishing," Contactmusic quoted Mirren, as saying.
