Alicia Silverstone’s teenage son is making his screen debut — albeit in a blink-and-you’ll-miss-it moment.
Speaking with PEOPLE about her new Christmas movie, A Merry Little Ex-Mas, the actress, 49, shared that her 14-year-old son, Bear, came along with her during filming and ended up having a small cameo in the film. “Bear, he brought a friend with him and they were extras for a day,” says Silverstone.
“Maybe two days,” amends the Clueless star, adding that her teenage son also hung out with costar Oliver Hudson’s son, Wilder, 18, and her other costar, Pierson Fodé, 33. “Pierson was very kind to them and playful with them.”
Asked specifically which scene her son is in, Silverstone says, “They were extras in the park where Pierson and I run to go to the sledding adventure with everyone.”
“You can see them in the back, and you can see them talking if you’re very careful,” she notes. “No one would ever notice this unless you’re looking for it. If you’re careful, you can see them scooting down the hill.”
A Merry Little Ex-Mas, which tells the story of parents who find themselves beginning to drift apart as they face becoming empty-nesters, stars Silverstone, Oliver, Wilder, Fodé as well as Jameela Jamil and Melissa Joan Hart. The rom-com premieres on Nov. 12 on Netflix.

This past June, Silverstone revealed to PEOPLE that she’d shared her iconic movie, Clueless, with Bear when he was just a preschooler. “I remember when my son was 5, when he first saw it,” she said at the time. “And the only reason I would allow that, because I don’t think it’s appropriate for 5 year olds, is because it was on that big screen that we saw it at the cemetery. He didn’t know what was going on.”
“The only thing he took away was the kiss at the end. He started kissing me more. It was so sweet,” she continued. “And I think he liked it. And then he’s liked it all along. I think he really likes this film.”
Last September, the actress was shocked to learn that her son was finally taller than her. Silverstone shared a cute cooking video with Bear on Instagram — and before cheffing up some vegan quesadillas, the mother-son duo stood face-to-face and back-to-back. It was then that Silverstone discovered Bear had outgrown her.
“Are you serious?” the proud mom exclaimed, before asking, “Where’s your mouth?” Bear then leaned forward to show that his mouth is well above his mom’s. Silverstone glared at the camera in disbelief.
Still not convinced that Bear is taller, she ordered, “Go back-to-back.” Once again, the teenager, who Silverstone shares with ex-husband Christopher Jarecki, is taller than his mom. “This happened overnight. I was taller than you last night,” she said to her son.
“I know,” Bear chimed in. “Crazy!”
