The award-winning TV legend died on Friday at age 99.
In a statement to People magazine, the late star's agent and close friend Jeff Witjas said: "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," Witjas said.
According to the outlet, a fabricated quote circulated about White's death on social media. Additionally, the news article cited by social media users doesn't contain the bogus quote – "Eat healthy and get all your vaccines. I just got boosted today" – or anything about vaccines.
Witjas previously confirmed that White did not receive a booster on Dec. 28.
White's penchant for comedy never seemed to fade, as she again found success on television with the sitcom "Hot in Cleveland," which ran from 2010-2015.
The star would have turned 100 on Jan. 17.
On Friday, Witjas said: "Even though Betty was about to be 100, I thought she would live forever. I will miss her terribly and so will the animal world that she loved so much. I don't think Betty ever feared passing because she always wanted to be with her most beloved husband Allen Ludden. She believed she would be with him again."
Ludden and White were married from 1963 until his death in 1981. According to Page Six, White's "very last word" was reportedly "Allen."
Actress Vicki Lawrence, who worked with White on the television series "Mama's Family," told the outlet that she reached out to co-star Carol Burnett when she learned of the news.
"I texted Carol and said, ‘This just sucks. I hate this. It’s just horrible to see the people you love so much go away,’" Lawrence said. "Carol wrote back and said, ‘I know, I know. I spoke to Betty’s assistant, who was with her when she passed, and she said the very last word out of her mouth was ‘Allen,'" Lawrence reportedly claimed to Page Six.
Lawrence added: "How sweet is that? I said, ‘That is so sweet. God, I hope that’s true. For all of us, I really hope it’s true, a lovely thought.’"
A rep for Burnett did not immediately respond to Fox News' request for comment.
