Billie Lourd Shows Her Son Great-Grandmother Debbie Reynolds’ Movie “Singin’ in the Rain”

The actress shares her two kids with husband Austen Rydell

Billie Lourd is taking a trip down memory lane.

On Monday, the Booksmart actress, 31, shared a post on her Instagram Story, showing her son Kingston, 3, engrossed in the movie Singin’ in the Rain. This 1952 film starred Lourd's grandmother, Debbie Reynolds, who passed away from a stroke on December 28, 2016, at the age of 84.

The photo shows the back of Lourd's son's head as he sits in front of the television, watching his great-grandmother donned in a pink flapper girl costume, singing. Staying with the color scheme, Lourd captioned the photo with three pink hearts.

However, Reynolds' movie isn't the only significant film she hopes to introduce her son to.

Last year at Fisher's Hollywood Walk of Fame ceremony, Lourd shared more about showing her kids her late mother Carrie Fisher's body of work as she honored her mother at Fisher's Hollywood Walk of Fame ceremony. "I can't wait to bring my kids here when they're old enough to understand how cool it is," she shared.

"I feel so lucky that even though they won't get to meet my mom, they will get to know a piece of her through Leia," she continued. "And I will get to tell them that the little lady in the TV is my Momby, their Grandmomby. Leia has become a family heirloom, and not just for my family."

The previous winter, Lourd opened up about her difficulty in balancing her grief for her mom and the joy of being a mom herself. Besides Kingston, she is also a mom to daughter Jackson Joanne, 15 months, with husband Austen Rydell.

"✨❤️✨It has been 6 years since my Momby died (feels like 2 but also like 705 at the same time?). And unlike most other years since she's died, this year, these past two weeks have been some of the most joyful of my life," Lourd wrote.

"Giving birth to my daughter and watching my son meet her have been two of the most magical moments I have ever experienced. But with the magic of life tends to come the reality of grief," she continued. "My mom is not here to meet either of them and isn't here to experience any of the magic."

"That's the thing about grief. I wish my Momby were here, but she isn't," Lourd said. "So all I can do is hold onto the magic harder, hug my kids a little tighter. Tell them a story about her. Share her favorite things with them. Tell them how much she would have loved them."
