Angelina 'bitches about Brad in her secret pregnancy diary'

Melbourne, July 3 (ANI): Mum-to-be Angelina Jolie has been maintaining a secret diary throughout the duration of her pregnancy - so that she can remember all the emotions she's going through and also vent feelings she has for Brad Pitt, it has emerged.

The diary is said to be "so intimate" that even partner Pitt is unaware of its contents.

"While she's been stuck on bed rest, Angelina is writing down all the changes she's going through psychically and emotionally," News.com.au quoted a source, as saying.

"This journal is very special to her and she's keeping it private, even from Brad. She said that maybe she'll let him see it one day, but for now it's just for her. She needs to have an outlet where she can vent - sometimes about Brad!" the source added.

Angelina, who is already a mother to four children, has been overwhelmed by emotion during this pregnancy - her second. (ANI)
