Todd Williamson/Getty Lourd, who is the daughter of Fisher and Bryan Lourd, has previously spoken about her childhood with the famous Star Wars actress. "I grew up with three parents: a mom, a dad and Princess Leia," Lourd wrote in an essay for Time in November 2019. "I guess Princess Leia was kind of like my stepmom — technically family, but deep down I didn't really like her ... When Leia was around, there wasn't as much room for my mom — for Carrie."

"I realized then that Leia is more than just a character. She's a feeling. She is strength. She is grace. She is wit. She is femininity at its finest," Lourd wrote, adding, "And no one could have played her like my mother. Princess Leia is Carrie Fisher. Carrie Fisher is Princess Leia. The two go hand in hand."
