The Hot in Cleveland
actress, 91, has made the 2014 Guinness World Records

"I was astounded when [Guinness World Records] called to tell me. Who? Me!?! It's such as honor," White says in a statement.
"The book has always been fascinating to me. I can't believe I'm now associated with it."
The actress, who made her TV debut in 1939 and has starred on shows including The Golden Girls
