With Halloween right around the corner, Amanda took to her Instagram Story to share her costume for the holiday.

She posted a photo of herself wearing gray mouse ears, which calls back to Mean Girls when Cady Heron (Lindsay Lohan) describes Halloween in “girl world” as “the one night a year where a girl can dress like a total slut and no other girls can say anything about it. The hardcore girls just wear lingerie and some form of animal ears.”

Gretchen Wieners (Lacey Chabert) then shows up at Amanda‘s character Karen Smith’s house wearing a leather dress and cat ears. Karen greets her wearing a black night gown and gray mouse ears, and when Gretchen asks her what she’s supposed to be, Karen declares, “I’m a mouse. Duh.”

Mean Girls fans are sure to get a laugh out of Amanda‘s costume idea!
