The mother-daughter duo of Carrie Fisher and Billie Lourd had us cracking up all night at the Star Wars: The Force Awakens premiere on Monday!

Lourd, 23, appears in the seventh installment of the Star Wars franchise with her mom, 59. While she has stated she is not playing Princess Leia's daughter, she does admit that her hairdo in the movie is a tribute to her mother's iconic character.

"We spent a really long time discussing it one day, because it was that important," Fisher told ET on the red carpet. "I had the baboon ass hairstyle, so who made out better?"

In all the excitement of the night, Fisher and Lourd got swept up in reminiscing over Lourd's first Star Wars memory -- an event that they each remembered a little differently.

"My first Star Wars memory was me kicking and screaming, because she was begging me to watch it," Lourd said. "I was like 4 years old."

"Do I seem like a beggar?" Fisher interrupted. "They did not hire me because I was a beggar."

"She begged me to watch it," Lourd countered. "I obliged."

"She was six!" Fisher insisted.
