The actress, 55, appeared on Thursday’s episode of The Tonight Show and revealed to Jimmy Fallon that her daughter once threw a 200-person party at their home for her 16th birthday. “First of all I want to ask you, 'cause you’ve been in so many classics — Breakfast Club, Pretty in Pink, but also Kissing Booth, Riverdale as well,” Fallon, 49, said. “I feel like — are you an expert on teenagers at this point?” “You would think,” Ringwald replied. “I think that people ask me to be a part of any teenage project like I’m the teen Budha or something, the patron saint of teenagers.

I’m not kidding.” Mathilda Gianopoulos and Molly Ringwald at the Rodarte x IMG New York Fashion Week party at Jac's on Bond at 26 Bond Street on February 10, 2023.
