Angelina Jolie will reportedly sign a book deal for her autobiography. With several publication houses currently in a bidding war for the rights to her autobiography, the 'Tomb Raider' star is expected to earn over £31 million.

"Whoever gets her will be sitting on a gold mine. Her book is guaranteed to top the bestseller lists in virtually every country on the planet and even an advance of that size would be recouped within weeks," predicts one source.

Apart from being an actress, Jolie is likewise active in her humanitarian acts. After recently undergoing a double mastectomy, she also serves as a big advocate for women health. According to one of her friends, the actress is now very excited to share her story to the world: "She has always wanted to do this and believes the time is now right. She has never known such peace and fulfilment in her life. There are demons in her past but she is in a place mentally and spiritually where she feels comfortable enough to write about them honestly and put them in context."

While the book is expected to be a tell-all tale, the source adds that there is only one exception: "No issues - apart from those that might damage her children's privacy - will be taboo."
