Reality TV star Heidi Montag is planning to pen a tell-all memoir about her life.
The 25-year-old, who recently announced her break-up with husband Spencer Pratt, will reveal details about her marriage and why her friendship with Lauren Conrad fell apart through the book.
"She'll talk about the control that Spencer exerted over her, which forced her to make bad decisions that ultimately got her kicked off 'The Hills'," contactmusic.com quoted a source as saying.
"A big chunk of the book will be about how Heidi befriended Lauren and how devastated she was when she ended up dumping her as her BFF. Maybe something positive will come out of it."
"She's happy to have people read the full story and make up their own minds," the source added.
