Betty White died from complications of a stroke, her death certificate revealed.
The Los Angeles County Department of Public Health document, which was obtained by TMZ, said the "Golden Girls" icon officially died of a cerebrovascular accident, which is a loss of blood flow to part of the brain, resulting in brain tissue damage.
Betty suffered the stroke six days before her Dec. 31 death, the certificate noted.
Although her condition between the time of her stroke and the date of her death isn't known, TMZ reported, "Betty was alert and coherent after the stroke, and she died peacefully in her sleep at home."
Betty's agent previously said that Betty died of natural causes, rebutting unfounded online claims stating otherwise.
"People are saying her death was related to getting a [COVID-19] booster shot three days earlier, but that is not true. She died of natural causes," the agent told People magazine, adding, "Her death should not be politicized — that is not the life she lived."
Betty's death came less than three weeks before she would have turned 100 years old.
On Jan. 3, "Mama's Family" star Vicki Lawrence — who worked with Betty on the show — told Page Six a bittersweet story about Betty's final moments. Vicki said she reached out to mutual friend Carol Burnett after hearing news of Betty's death.
"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,'" Vicki shared. "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.'"
Betty's late third husband, "Password" host Allen Ludden, died from stomach cancer in 1981.
"How sweet is that?" Vicki added. "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.'"
