Betty White is dead at age 99, just weeks before what would have been her 100th birthday on Jan. 17.

TMZ was the first outlet to report on White’s death, while a rep for the Los Angeles Police Department told ET that the primary investigation indicated White died of natural causes, with “no evidence of foul play.”

White’s agent and close friend Jeff Witjas confirmed the news to People.

“Even though Betty was about to be 100, I thought she would live forever,” said Witjas in a statement. “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.”

White is a bona fide television icon, with a career that spanned nine decades. She racked up hundreds of screen credits that included such classic television shows as “The Mary Tyler Moore Show” and “The Golden Girls”.

Beginning her acting career in radio, White appeared in the very first, experimental television broadcast. In the 1940s she was tapped as “girl Friday” on a local Los Angeles talk show “Hollywood on Television”, which aired for five and a half hours each day, six days a week.

Filling all those hours honed White’s skills as a performer, which were on display when she starred on 1953’s “Life with Elizabeth”, one of television’s first sitcoms.

In 1961, a chance appearance on the game show “Password” led White to meet the love of her life, and she and the show’s host, Allen Ludden, wed a year later. The couple remained happily married until Ludden’s death in 1981.

It was White’s role on “The Mary Tyler Moore Show” in the 1970s that cemented her as a star. White would got on to win two Emmys for her portrayal of Sue Ann Nivens, man-hungry host of TV cooking show “The Happy Homemaker”.

In the following decade, White became part of another enduring TV hit when she was cast as ditzy Rose Nylund on “The Golden Girls”, which ran from 1986 until 1992. White received an Emmy nomination for Outstanding Lead Actress in a Comedy Series in each year of the show’s run, winning in 1986.

White maintained a busy schedule as an in-demand actress during the decades that followed, highlighted by her Emmy-nominated series regular role in sitcom “Hot in Cleveland”, and numerous guest-starring appearances, including an Emmy win for a guest spot on “The John Larroquette Show”.

White also received Emmy nominations for her appearances on “Suddenly Susan”, “Yes Dear”, “The Practice” and for hosting a 2010 episode of “Saturday Night Live”, the result of a social media fan campaign.

Throughout her career, White was one of Hollywood’s most vocal animal-rights advocates, working with the Los Angeles SPCA since the 1960s.

White was also the author of several books, including If You Ask Me (And Of Course You Won’t), in which she described her philosophy on aging.

“It’s not a surprise, we knew it was coming — make the most of it,” she wrote. “So you may not be as fast on your feet, and the image in your mirror may be a little disappointing, but if you are still functioning and not in pain, gratitude should be the name of the game.”

Following news of White’s death, numerous celebrities have been paying tribute on social media.
