White’s agent, Jeff Witjas, is debunking a fake quote attributed to White that falsely claims that, three days before her death, she said "I just got boosted today." Says Witjas "Betty died peacefully in her sleep at her home. People are saying her death was related to getting a booster shot three days earlier but that is not true. She died of natural causes. Her death should not be politicized — that is not the life she lived." ALSO: Vicki Lawrence: Carol Burnett told me White's last word was her late husband Allen Ludden's first name.
