Angelina Jolie is reportedly planning an autobiography based on her Hollywood career and work travelling the globe with the U.N. "She's writing about her experiences adopting children and becoming a new mom," a source told Star magazine. "She also wants to include memoirs from all other mothers she has met around the world and got to know. She's going to include stories about the orphans that she's met, and she's hoping it will encourage people to adopt and help others understand why she travels and is so active as a goodwill ambassador."
