Richards chose not to dish on the details of her 2006 divorce from Sheen when she penned "The Real Girl Next Door."
"I also didn't want to be disrespectful to [Charlie] and what our marriage was," Richards told "Access Hollywood" last week. "I also included a lot of good times and good memories."
And in return, Sheen took to Twitter telling Richards, "Your book rocks!!" He also did Richards a big favor by linking to "The Real Girl Next Door" page on Amazon.
The couple have two daughters from their four-year marriage.
