Meg Ryan pays heartfelt tribute to Rob Reiner

She wrote on Instagram alongside a black-and-white photo of herself dancing with Rob while making When Harry Met Sally: "Oh how we will miss this man …

"Thank you, Rob and Michelle, for the way you believe in true love, in fairy tales, and in laughter. Thank you for your faith in the best in people, and for your profound love of our country."

Ryan went on to express her hope that "some good may come" from the couple's tragic deaths.

She added: "I have to believe that their story will not end with this impossible tragedy, that some good may come, some awareness raised … I don't know, but my guess is that they would want that to be hopeful and humane, to be something that brings us all to a greater understanding of one another and to some peace."
