Only one Carrie Fisher attended Comic-Con this weekend, but hundreds of Princess Leias made the trek to the San Diego celebration – and Fisher’s daughter Billie Lourd says that her mother does not grasp her Comic-Con popularity.

Lourd, one of the stars of Fox’s horror-comedy hybrid Scream Queens, tells PEOPLE that her mother, the original Princess Leia, only made an appearance at Comic-Con to support her daughter at the premiere of her show. Lourd recalls that Fisher quipped, “I don’t get it, babe. I went to this premiere, and I’m not there to take pictures. I’m there to watch the premiere. And people are wanting to take pictures with me.”

Lourd makes a lighthearted jab at her famous mother’s lack of preparation – after all, she showed up to the premiere sporting blue jeans and a messy hairdo: “I’m like, ‘Mom, you’re Princess Leia. You got to remember that … you’re at Comic-Con, so, like, maybe you should have brushed your hair,’ ” Lourd jokes.

The mother-daughter duo will share the screen in the upcoming blockbuster Star Wars: The Force Awakens, though Lourd claims that she will not be playing the child of Fisher’s Princess Leia.

In Scream Queens – which set up its own shriek-inducing ride at Comic-Con – Lourd steps out of her mother’s shadow as a sorority girl in a tight-knit cast of big-name actors including Lea Michele, Keke Palmer, Emma Roberts, Nick Jonas, Abigail Breslin, Ariana Grande and Jamie Lee Curtis.

“It’s like camp,” Lourd says of the Scream Queens production process. “It’s so much fun. We have sleepovers. We go to dinner. It’s like we’re always in each others’ trailers. It’s so fun.”
