Where does octogenarian Betty White get the energy? The actress, whose stock has been surging since she followed The Proposal by hosting last season’s best episode of Saturday Night Live, has made a deal with G.P. Putnam’s Sons to write two books. First is Listen Up!, described by the publisher as a memoir of lessons learned over a long career but especially the last 15 years. Then she’ll write The Zoo and I: Betty and Her Friends, which is lighter lifting for her since it’s stories and photos of zoo animals. The books sold at auction and Putnam’s walked away with North American hardcover and paperback rights and e-book rights.
