Few people in the twilight of life have enjoyed the type of career resurgence as Betty White. But if you ask her, she'd probably say that she's just getting started. The actress brings so much energy and entertaining sass to her work that it's easy to forget she's almost 90 years old.

Beyond her hit television series, "Hot in Cleveland", animal advocacy projects and calls for her to host the Oscars (she says "no way"), White has now taken on the task of writing two books.

G.P. Putnam’s Sons announced Wednesday that the actress has signed a two-book deal, with the first one — “Listen Up!” — due out next spring. The book focuses on her more than six decades in Hollywood, giving the BW commentary on everything from sex to love and aging.

The second book, due out in 2012, will focus on her relationship with her “zoo animal friends” and be called “The Zoo and I: Betty and Her Friends”. White is a longtime Los Angeles Zoo Board member. “Much as I love what I do for a living in show business, I love writing even more — so I am thrilled to be working on not only one new book but two of them,” she said.

"Zoo" isn't the first animal-themed book by White. Back in 1992, she wrote "The Leading Lady: Dinah's Story" about a former guide dog she adopted that slowly went blind.

Still can't get enough? White has a hilarious calendar coming out this Fall benefiting the Morris Animal Foundation.
