Jennifer Aniston will never get over Brad Pitt leaving her for Angelina Jolie, and woe betide the man or woman that dares to tell her that she should just get over it. Now, she's planning a tell-all book about the situation, and supposedly, this is making her TOTES RIVAL 4EVAH Angelina Jolie a nervous wreck! 

According to IBN, Angelina finds this whole thing ridiculous (and what grown woman wouldn't) -- marriages end, and they get with new partners, all the time. She also feels that, after nearly 10 years of being with Brad, Jennifer really needs to get a grip on reality -- especially since Jennifer is supposed to be getting married to someone else (Justin Theroux) pretty soon.

"Angelina's worked hard to build up her image as a humanitarian and separate herself from the public outcry when she got together with Brad. She felt the whole 'Team Jen' and 'Team Ange' thing had finally died a death and that the perception of her being a husband stealer was in the past, but then she heard about the book offer," a friend of Angelina's told the site.

But don't tell that to Mean Girl Jen -- Angelina totally stole her husband, and now it's time for literary vengeance! Let's just hope that she doesn't murder Angelina in avatar form in a follow-up roman a clef. 

And according to The Hindustan Times, we just might be able to anticipate that. After all, Jennifer feels this is very therapeutic for her to do! "If Jen does sign a book deal, she knows the chapter on Brad and Ange will be the hardest for her to write -- but it will also be the one everyone will be after. Jen doesn't want to spark any new rows, but there's so much history involved that it's inevitable," says the paper.
