Diane Keaton's daughter, Dexter, is honoring the late actress on what would have been her 80th her birthday. "I miss you, mom 💔🕊️Thank you @winterstone for my forever reminder of my wonderful mom 🖤🤍🖤," Dexter, 30, captioned a post via Instagram on Monday, January 5, showing off a new tattoo to celebrate Keaton's legacy. One picture showed Dexter's tattoo up close, which said, "La Di Da" with a small heart, a reference to the actress' famous line in 1977's Annie Hall.
