The Hills star Heidi Montag is threatening legal action over Spencer Pratt's plans to write a tell-all book about their relationship. Montag, 23, is furious with Pratt for saying he is going to write a book about their private life. Heidi told entertainment site TMZ: 'This is exactly why I left him, right now I'm looking into my legal options.' Spencer, 27, earlier revealed he will open up about his failed marriage with the reality star and her relationship with her mother, Darlene Egelhoff, in the book. He told Us Magazine: 'My last book, How to be Famous, didn't make the New York Times best-seller list because it was in the self-help section. 'This one will be totally different, I'm not holding anything back.' The pair are expected to be officially divorced on Valentine's day 2011.
