"I love sharing my stories and experiences with people and connecting to them on both a humorous and emotional level," Spelling, 36, tells PEOPLE exclusively. "The response to my first two books has been so amazing that I wanted to write a third one for my fans."
Those fans can expect the actress to dish on the very latest in her public life, including her reaction to the tabloid scrutiny of her weight, her infamous relationship with mom Candy, with whom she just reconciled, life with husband Dean McDermott and their two children, and whether they might be adding to their brood in the near future.
"With two kids it's hard to find down time to write so I often write during their nap time," Spelling says. "Whenever something happens that makes me laugh or if I remember something in the middle of the night that I want to share, I jot the experience down."
Spelling wrote the book in between filming for the fifth season of her reality show, Tori & Dean: Home Sweet Hollywood, which premieres on Oxygen in the spring, and working on her jewelry and kids' clothing line.
"I like to write in our family room since so many of my stories revolve around my family or from my bed cause it's so damn cozy! The biggest challenge was finding the time," she says. "The biggest joy was appreciating how lucky I am to have that challenge!"
The new book follows her first two New York Times-bestselling efforts, Mommywood and sTORItelling, which combined have more than 800,000 copies in print.
