Mandy Moore, who starred as Diane’s daughter in 2007’s Because I Said So, offered a lengthy statement on Instagram:
“They say don’t meet your heros but I got to work with one of mine and even call her ‘mom’ for a few months. An honor of a lifetime. What an incandescent human Di is and was. I am so sad she’s gone for all the reasons but also because it felt like she’d be here forever, dazzling us with her talent and charm (and her style, c’mon)!!! One of the very best to ever do it. All my love to her children and loved ones.”

Jane Fonda, who starred alongside Diane in 2018’s The Book Club, also took to Instagram to share her remorse:
“It’s hard to believe…or accept…that Diane has passed. 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 world view. Unique is what she was. And, though she didn’t know it or wouldn’t admit it, man she was a fine actress!”
Awww.
Diane and Jane’s fellow The Book Club co-stars Mary Steenburgen, and Candice Bergen also offered somber statements. Mary wrote:
“Diane was magic. There was no one, nor will there ever be, anyone like her. I loved her and felt blessed to be her friend. My love to her family. What a wonder she was!!!”
And Candice shared:
“This is a huge loss, both personally and for all of us. Diane was a true artist – tremendously gifted and uniquely talented in so many disciplines, yet also modest and wonderfully eccentric. I will miss her terribly.”
So, so sad.
Back on Instagram, Diane’s The First Wives Club co-stars Goldie Hawn and Bette Midler shared their grief-stricken reactions. See (below):
Steve Martin, who acted alongside Diane in Father of the Bride, reflected on a sweet sweet memory in his own post:
