For her second festive outfit, Carey chose to take a page out of Rachel McAdams' playbook by portraying her Mean Girls character, Regina George.

Carey recreated McAdams' outfit from the scene in the film in which her white tank top is cut with two holes by Lizzy Caplan's character, Janis Ian. The performer paired the shirt with a purple bra, black miniskirt, and black pointed-toe pumps.

She debuted the look in an Instagram video alongside the caption, "whatever I'm getting cheese fries #notyet." The clip had Blondie's "One Way Or Another" playing in the background, along with an animated graphic that read, "That's so fetch."

The singer's fans were quick to make additional references to the iconic 2004 film in the comment section. One fan wrote, "This one time I saw Mariah wearing high heels and a gown to the pool… soo I wore high heels and a gown to the pool." Another fan left a comment that read, "One time Mariah punched me in the face. It was awesome!"

Fans also complimented Carey's love of the holiday season. One social media user wrote, "OK, so first queen of Christmas and now queen of Halloween!!!"

Carey has taken her love for the holidays a step further this year by appearing in a new holiday campaign for The Children's Place.

The music icon dressed up in festive attire to star in the campaign alongside her 12-year-old twins, Moroccan and Monroe, with whom she shares with her ex-husband Nick Cannon. She raved about her love for Christmas while chatting about the campaign exclusively with PEOPLE.

"The Children's Place is a household name, and it truly dominates the children's apparel space, so I've always been a fan of theirs," she said. "Secondly, I'm just someone who absolutely loves the holidays. I mean, that's obvious, but I really do love holidays, specifically Christmas."

Carey told PEOPLE that she and her kids celebrate the holidays by wearing matching pajama sets.
