The 91-year-old actress has worked steadily since the late '40s, though she's most well known for her role on "The Golden Girls" in the late '80s. When the show went off the air in 1992, Betty continued to keep busy with small roles on television and film. But in 2009 Betty made a big splash starring alongside Sandra Bullock in the hit rom-com "The Proposal." Betty rode her ability to play the sweet old lady with a dirty sense of humor all the way to the bank. And now she's back on television with a starring role in "Hot in Cleveland," proving that being a comeback kid has nothing to do with age!
