Tori Spelling Writing Another Book

The actress, 35, is reportedly planning a new book -- tentatively titled Mommywood, which will focus on her life as a Hollywood princess-turned-parent, according to publishers Simon & Schuster.

The new book, already listed on Amazon.com and scheduled to hit the shelves in April 2009, is expected to focus on the birth and growing pains of 1-year-old son Liam and newborn Stella. She is "doing great," Spelling -- who's currently starring in Tori and Dean: Home Sweet Hollywood and preparing to reprise her role in the new 90210 -- recently told PEOPLE. And "little man" Liam is adjusting to being a big brother. "At first he was unsure," she said. "But now he gives her kisses goodnight. It's really sweet."
