Diane Keaton's daughter, Dexter, paid tribute to her late mom on Mother's Day. Sharing an Instagram post on Sunday, May 10, Dexter, 30, posted a carousel of three beautiful mother-daughter images alongside a caption. "First Mother's Day without you. I miss you more than words can say. Missing her voice, her hugs, her presence, and everything that made her home," she wrote. "I love you, Mom 🤍." The photos showed Dexter as a child at the beach with a smiling Keaton, as well as the pair celebrating Dexter's wedding day in 2021 and Keaton giving her daughter a kiss on the cheek in a garden.
