Update: Betty White — who was getting ready to celebrate her 100th birthday in a matter of weeks, on Jan. 17, 2022 — sadly passed away on Dec. 31, 2021.

In an exclusive statement she shared with Fox News Digital via her publicist on Thursday, Dec. 30, 2021, about her long and happy life, she captured a great deal in just a few lines.

It was one of her last statements to the media before her death.

White was born the only child of her "beloved mother," homemaker Christine Tess, and her dad, Horace Logan White, a lighting company executive.
