Billie Lourd calls grieving Carrie Fisher, Debbie Reynolds 'surreal and impossible'
"It's so hard to talk about," Lourd told DeGeneres, "and I don't know, it's like if I say that I'm doing good, I'm too happy. If I say that I'm not doing good then I'm a mess. So, it's like really hard to know what to say about it because it is just so surreal and impossible to deal with."
With her burgeoning acting career, Lourd, 25, is following in her mother and grandmother's footsteps. However, her mom and dad, talent agent Bryan Lourd, didn't encourage her initially.
When Lourd surprised Fisher with how comfortable she felt on a movie set, Fisher changed her mind.
"I came home and my mom said, 'You know, this is really weird that you're comfortable here. This is one of the most uncomfortable environments in the world. If you're comfortable here, you should (act),'" Lourd recalled.
Lourd and Fisher both appear in 2015's Star Wars: The Force Awaken and in Star Wars: The Last Jedi, slated to hit theaters in December.
Of acting alongside her mom, Lourd told DeGeneres, "It was really incredible for us to get to have that experience together."
