The actress will chronicle her time on "Beverly Hills, 90210," her relationships with her co-stars and her new life as a single mother following her divorce from Peter Facinelli in the book, titled "Deep Thoughts From a Hollywood Blonde."

Announcing her literary news, Garth says, "The past few years have been full of changes. Now I'm on my own with my three kids, and I just crossed that tricky invisible line into my forties. Maybe because of all these things or maybe despite them, I feel like another chapter in my life is just beginning. This book is my story about where I've been and where I'm headed -- and what I've learned along the way."

"Deep Thoughts From a Hollywood Blonde" is set to hit stores in April.
