In an interview on the "Today" show Tuesday, Charlie Sheen's second ex-wife talked about her just-published book, "The Real Girl Next Door," and Sheen's presence in it.

Host Matt Lauer says the book is not a Sheen-basher and says at one point, "You said, 'This is not the man I married. This is the man I divorced.'"

Richards responds, "The man I fell in love with is very compassionate, humble, has a wonderful heart and the behavior that a lot of us saw in the last six months is not the person I met and fell in love with."

When asked about the moment when she knew her marriage with Sheen was over, Richards demurs, saying she wanted to touch more on the feelings that go along with divorce, not the details. Richards says she also addresses her relationship with Richie Sambora and her mother's illness in the book.

The 40-year-old actress and former Bond girl recentlyadopted a baby daughterwhom she named Eloise Joni Richards. She has two daughters Sam, 7,and Lola, 6, with Sheen.

Sheen was fired from the CBS sitcom, "Two and a Half Men," on which he starred for eight seasons, in March. He was replaced by Ashton Kutcher. Sheen recently announced he's working on a new sitcom called "Anger Management," loosely based on the 2003 Jack Nicholson-Adam Sandler movie of the same name.
