'Real Housewives' star Taylor Armstrong: I'm Writing a Tell-All

"Real Housewives of Beverly Hills" star Taylor Armstrong -- whose estranged husband committed suicide earlier this year -- is writing a tell-all book about her relationship.

It's called "Hiding from Reality: My Story of Love, Loss, and Finding the Courage Within" -- and the 272-pager is set for release in February 2012.

Taylor claims she's writing the book to raise domestic violence awareness -- and will detail the ins-and-outs of her relationship with her late husband Russell Armstrong ... who she claims physically abused her.
