Perhaps nobody is feeling the stunning losses of both Carrie Fisher, and her mother, Debbie Reynolds, more than Todd Fisher, their brother and son, respectively.

Todd took to Twitter on Thursday and posted a heartbreaking drawing of Carrie and Debbie's iconic big-screen characters -- Star Wars' Princess Leia and Singin' in the Rain's Kathy Selden -- embracing one another.

"This is a beautiful love story to witness in my 58 years," Todd tweeted. "I miss them both so much. Love is everlasting."

Debbie died on Wednesday, just one day after Carrie's death on Tuesday at the age of 60. An ambulance responded to a medical call from Debbie's Beverly Hills home at 1:02 p.m. and transported the Hollywood legend to Cedars-Sinai Medical Center. She died shortly thereafter at the age of 84.

"She missed her daughter and wanted to very much be with her," Todd told ET about his mother's state of mind during her final hours. "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."

The mother-daughter duo was admirably open about their complicated and close relationship throughout the years.

"Carrie and I have disagreements and stalemates, but we still walk away loving each other," Debbie told The New York Times in 2010.

Last month, Carrie called her mother "an immensely powerful woman" during an interview with NPR.

"She's an extraordinary woman. Extraordinary," Carrie gushed. "There's very few women from her generation who worked like that, who just kept a career going all her life, and raised children, and had horrible relationships, and lost all her money, and got it back again. I mean, she’s had an amazing life, and she’s someone to admire."
