Betty White too busy to retire

Actress Betty White

Betty White joked that Facebook seemed like a huge waste of time during her wildly successful hosting gig on Saturday Night Live. Turns out she wasn't kidding.

“That was a line that was written for me, and I would have said it myself, but I didn't know what Facebook was, and I still don't,” the actress said Wednesday at the Television Critics Association's winter meeting in Los Angeles.

White, who turns 89 on Jan. 17, is enjoying a career resurgence.

“You've had such an overdose of me lately,” she said. “I'm trying to cut down. I really am.”

At the same time, White finds it difficult to stay home.

“You spend your career thinking if you say no, they'll never ask you again, and if you don't take the job that may be the end of it,” she said. “My mother taught me to say no when I was a girl, but that wasn't about show business.”
