Mia Farrow has reacted to Diane Keaton’s shocking death following their complicated history.

“She was an absolutely wonderful actress — and a rare and fascinating person,” Farrow, 80, wrote about Keaton via Instagram on Saturday, October 11. “Thoughts with her children and sisters. Rest in peace Diane.”

Keaton’s spokesperson announced her death at age 79 and asked for “privacy” on behalf of the Oscar winner’s family on Saturday, though no official details have been released. (Keaton is survived by her two children, daughter Dexter and son Duke, whom she adopted as a single mom well into her 50s.)

Farrow and Keaton have a long history through both their professional and personal relationships with actor-director Woody Allen.
