DIANE KEATON DEAD AT 79 IN CALIFORNIA FOLLOWING LEGENDARY HOLLYWOOD CAREER: REPORT

Keaton died at the age of 79, her family confirmed to People magazine.

A close friend of the Hollywood icon told the outlet that Keaton's health had rapidly declined. 

"She declined very suddenly, which was heartbreaking for everyone who loved her," a friend of the Oscar winner told People. "It was so unexpected, especially for someone with such strength and spirit."

"In her final months, she was surrounded only by her closest family, who chose to keep things very private. Even longtime friends weren't fully aware of what was happening," the friend added. 

Grammy and Oscar-winning songwriter Carole Bayer Sager detailed her final visit with Keaton just weeks before her death. 

"I saw her two or three weeks ago, and she was very thin," Sager, who co-wrote Keaton's single, "First Christmas," told People. "She had lost so much weight."

"She had to go to Palm Springs because her house had been damaged inside [from the L.A. wildfires], and they had to clean everything," she continued. "She was down there for a while, and when she came back, I was kind of stunned by how much weight she'd lost."

Despite her health struggles, said Sager, "she was a magic light for everyone."

"I just loved her. She was so special, she just lit up a room with her energy. She was happy and upbeat and taking photographs of everything she saw. She was completely creative; she never stopped creating."

Another friend of the star said Keaton "was funny right up until the end."

"She lived exactly how she wanted to, which was on her own terms, surrounded by the people and things she really loved," the friend told People. "In these last few years, she kept a close circle and she liked it that way. She was funny right up until the end and she had this way of making even ordinary moments feel special. That was just who she was."

After news broke of Keaton's passing, there was an outpouring of tributes to the Hollywood legend from her former co-stars and other celebrities.

She continued: "How do we say goodbye? What words can come to mind when your heart is broken? You never liked praise, so humble, but now you can't tell me to 'shut up' honey. There was, and will be, no one like you. You stole the hearts of the world and shared your genius with millions, making films that made us laugh and cry in ways only you could."

"I was blessed to make 'First Wives Club' with you, our days starting with coffee in the makeup trailer, laughing and joking, right through to the very last day of filming," Hawn added. "It was a roller coaster of love.

"We agreed to grow old together, and one day, maybe live together with all our girlfriends," Hawn wrote. "Well, we never got to live together, but we did grow older together. Who knows… maybe in the next life.
