If you know...you know. MERRY CHRISTMAS EVERYONE! 😂❤🤶🏻🎄🎁

This holiday season, Hailee Steinfeld paid tribute to Mean Girls.  

The “Most Girls” singer shared a video on Instagram in which she nails the choreography to the iconic “Jingle Bell Rock” scene from the film. After the thigh slap that had Cady Heron’s parents looking uncomfortable, Steinfeld burst out laughing. 

 While she ditched the red and white Mrs. Clause outfits Lindsay Lohan and Rachel McAdams wore in the film, Steinfeld still looked festive in a glittery gold mini dress.  

“If you know…you know,” she captioned the clip. Watch the original scene for comparison below.
