1/7/2012 UPDATE: The LA Zoo is celebrating Betty White's 90th birthday this month with a cake for the first 900 people through the gate and a special scavenger hunt. Betty won't be there; she's too busy! We taped this interview last summer.

It's true, and when she's petting the tapir, she's thinking about the koala, and possibly the elephant. Betty White, America's sweetheart and author of the memoir "If You Ask Me (And of Course You Won't)," talks with KPCC's John Rabe about the LA Zoo (and its upcoming Beastly Ball fundraiser), acting in "Advise and Consent" under Otto Preminger, and about looking like a grandma.
