Many fans probably don't know that Robyn Lively played an integral part in her younger sister, Blake Lively, and her husband, Ryan Reynolds' 2012 wedding. That's because she performed the "Finest Hour" dance from her 1989 hit movie, "Teen Witch." "[It was] the highlight of the entire wedding," Robyn told Us Weekly, adding that she roped their brother, Eric Lively, into playing the role of Brad in her recreation of the movie sequence. Her older sister shared, "It was really pretty amazing. It's one of her favorite movies."

On top of performing the dance number, Robyn also wore a "blue tube dress with a tutu," similar to what her character, Louise Miller, had on in the film. Blake seemed to like that too because just a few years later in 2016, the star wore an outfit that was apparently inspired by that look while promoting her movie, "The Shallows." She, of course, wore her hair in big '80s curls, just like her sister, Robyn, did in the movie.

While "Teen Witch" came out when Blake was just a baby, she's not the only person in her age group to have an appreciation for the film. In 2022, Robyn even told People that to this day, it's the role she's most recognized for. "People absolutely love that film, and it's resonated with so many generations," she said. "It's so dear and beloved to me because of that."
