Former first lady Nancy Reagan died Sunday at the age of 94.
The news was first reported by TMZ, citing a "close family member," and confirmed by a spokeswoman. The Reagan Library said in a statement that the cause of death was "congestive heart failure."
The widow of former President Ronald Reagan had been hospitalized in October 2014 with a fractured pelvis.
She served as first lady from 1981 to 1989 and was known for her work in combating youth drug abuse through the "Just Say No" campaign.
She was born Anne Frances Robbins on July 6, 1921, in New York City. When her stepfather adopted her in 1935, she took his last name of Davis. She majored in theater at Smith College in Massachusetts.
In 1951, she met her future husband when he was president of the Screen Actors Guild and she was a Hollywood actress billed as Nancy Davis. They married in Los Angeles in 1952 and had a daughter, Patti Davis, and a son, Ron Reagan.
"My life really began when I married my husband," Nancy Reagan often said. She even referenced the quote in her 1989 book My Turn.
