Betty White has died at 99, reports say. The legendary "Golden Girls" star was known for her decades-long career in television. There are stars whose deaths are a surprise because, let’s face it, we forgot they were still alive. White’s death on Dec. 31 is a shock because she was so incredibly alive, from her start as a TV ingénue to her reign as America’s favorite senior citizen. Surely we can be forgiven for thinking she was always with us, and always would be. White died Friday, her agent and friend Jeff Witjas confirmed to People and Deadline. A spokesperson for the Los Angeles Police Department confirmed to USA TODAY that they “responded to a death investigation call around 9:30 this morning," but declined to provide a name. She was set to celebrate her 100th birthday on Jan. 17 and had big plans to do so. On Dec. 17, she invited fans via a tweet to mark the major milestone with "100 Years Young," a nearly 2-hour film about her with cameos from White's friends including Ryan Reynolds, Tina Fey, Robert Redford, Lin Manuel- Miranda, Clint Eastwood, Jimmy Kimmel and others. From her very first television series, "Life With Elizabeth," there has hardly been a time when she has not been a regular presence in our homes: From "Date With the Angels" through "The Mary Tyler Moore Show," "The Betty White Show," "Mama’s Family," "The Golden Girls," "Boston Legal," "Hot in Cleveland" and "Betty White’s Off Their Rockers."
