Before you queue up Mariah Carey’s collection of Christmas hits and welcome the holiday season, here’s one last Halloween treat to extend your sugar coma.

Your honor, Camila Cabello dressed up as one the greatest to ever reign Genovia: Princess Mia Thermopolis.

On Tuesday, the singer-songwriter attended the biggest bash of the year, Heidi Klum’s highly anticipated Halloween soirée at Marquee in New York City.

Channeling the 2000s Disney classic Princess Diaries, the star served a modern-day version of Princess of Genovia in a white micro-minidress with a sweetheart neckline and boned corset detailing.

A pair of white slingback heels with sparkly bows, coordinating satin opera gloves, and a bedazzled black Prada handbag rounded out her Mia-inspired ‘fit.

She styled her long brunette hair in a tousled top knot bun with forehead fringe as she accessorized with a blinged-out tiara, black oval sunglasses, and black portable headphones — a spitting image from the Princess Diaries movie poster.

As for her glam, she complemented her glowy complexion with bold brows, rosy cheeks, and a glossy pink lip.

It was a star-studded night for Heidi’s epic annual bash, with the queen of Halloween herself in attendance, of course.

Taking home the best over-the-top costume of the year (leaving last year’s worm in the dust), the model, TV host, and mother unveiled her extravagant peacock costume that took an entire team to come to life.

Shutting down the red carpet in a bright blue, skin-tight velvet bodysuit, she completed the look with an elaborate turquoise avian head prosthetic with intricate lashes and a beak on her face.
