Bette Midler, who starred alongside Keaton in The First Wives Club, shared:

“She was hilarious, a complete original, and completely without guile. What you saw was who she was … oh, la, lala!”

Kimberly Williams-Paisley, who played her daughter in Father of the Bride, reflected:

“Working with you will always be one of the highlights of my life. Thank you for your kindness, your talent, and above all, your laughter.”

Steve Martin, her Father of the Bride co-star, simply wrote,

He also shared a playful interview moment where Martin Short asked Keaton who was sexier—him or Steve. With her trademark deadpan humour, she replied:
“I mean, you’re both idiots.”

Goldie Hawn offered a heartfelt farewell:

“How do we say goodbye? You never liked praise, so humble. There was, and will be, no one like you.”
