While further details regarding the decline in her health were not shared, the Father of the Bride star’s longtime friend Carole Bayer Sager shared that she had not been doing well in the weeks leading up to her death. 

“She was very thin," Carole told People of their recent visit. "She had lost so much weight."

For her friends, the news was shocking. 

"It’s hard to believe...or accept…that Diane has passed," her Book Club costar Jane Fonda wrote in an Instagram post Oct. 11. "She was always a spark of life and light, constantly giggling at her own foibles, being limitlessly creative... in her acting, her wardrobe, her books, her friends, her homes, her library, her worldview. Unique is what she was. And, though she didn’t know it or wouldn’t admit it, man she was a fine actress!"

And for her mentees throughout the years, they couldn't help but reflect on how she impacted them.

"She was one of my first mentors in this business," Reese Witherspoon said during an event the day of her passing. "I was 15 years old and I was from Nashville, Tennessee, and I didn't know anybody.”

She added, "She really took the time to pull me aside and say, 'Stand up straight, OK? I want you to have good posture. If you're gonna be an actress you got to work on your posture.’”

“So, for Diane, watch one of her movies," Reese shared. "And wear like a really cool, interesting outfit, black and white. Take a cool picture and just live your dream. Just be your unique, interesting self. I think Diane would be really happy. Rest in peace, Diane.”
