Singing alongside Ashley Park, who originated the Broadway role of Gretchen Wieners for the 2018 musical Mean Girls, the two sang a cover of Swift’s 2011 song and Lily Allen’s “F**k You.” “@taylorswift’s ‘Mean’ sprinkled with as many ‘Mean Girls’ references as possible SEE THE FULL VIDEO IN LINK IN BIO #Repost@ashleyparklady,” Seyfried wrote on Instagram Friday with a video of the performance. “Plastics unite tehehehe 💕 @mingey Dedicated to all the Gretchens and Karens out there!” the post continued. “Stay nice 🚺🥰 #meangirls (thanks to all the amazing @wtfestival apprentices and cabaret staff who quite literally made this performance happen, costumes included) https://youtu.be/CxdtBvm-K5Q.” J.

I just want to feel OK again.” Park, 28, added, “Boo, you whore.” Together they sang, “All you are is mean and a liar and pathetic and a fugly slut and mean,” changing Swift’s lyrics to include dialogue from Mean Girls.
