In subsequent tweets, Cher let the world in on the last time she spoke to her movie mom. "Heard Olympia Was Sick So Called Her Daughter & Said Could I Talk 2 Her," the 74-year-old tweeted. "She Said 'She might Not HEAR or SPEAK.' I Called In 2 The Receiver 'Olympia It's Cher, I [love] You.' Remember Moonstruck, She Said 'oh cher, I [love] you 'She Was Weak But Happy. RIP O."

But Cher wasn't done addressing how the passing of her co-star and friend impacted her, going on to tweet, "You never think about Friends, Loved Ones Leaving, But Thank God We Can See Them."

The beloved performer then quoted a scene from the movie that united her with Dukakis, tweeting, "Rose 'DO YOU LOVE HIM LORETTA!?' Loretta 'NO' Rose 'GOOD.' 'CAUSE WHEN YOU LOVE THEM THEY DRIVE YOU CRAZY, BECAUSE THEY KNOW THEY CAN.'"
