"She missed her daughter and wanted to very much be with her," Todd says. "She had been very strong the last several days. [There was] enormous stress on her, obviously. And this morning she said those words to me and 15 minutes later she had a stroke and virtually left."
Carrie died Tuesday morning after going into cardiac arrest aboard a transatlantic flight from London to Los Angeles last week. She was 60.
Reynolds took to Facebook later that day to mourn her "beloved and amazing" daughter.
"Thank you to everyone who has embraced the gifts and talents of my beloved and amazing daughter," she wrote. "I am grateful for your thoughts and prayers that are now guiding her to her next stop."
On Wednesday, an ambulance responded to a medical call from Reynolds' Beverly Hills home at 1:02 p.m. and transported the Hollywood icon to Cedars-Sinai Hospital. She died shortly thereafter at the age of 84.
Reynolds is perhaps best known for her roles in films such as Singin' in the Rain and The Unsinkable Molly Brown, but she was also revered for her philanthropy. In February, she was feted with the Jean Hersholt Humanitarian Award at the 88th Academy Awards, thanks to her founding work with the Thalians, an organization designed to increase awareness about mental health.
