JoJo Siwa's Draco Malfoy Halloween Costume Is Proof Polyjuice Potion Exists

JoJo Siwa solemnly swears she's up to no good. In preparation for Halloween, the "Boomerang" singer pulled on her best scowl and a pair of black-and-green robes to transform into Hogwarts's most entitled first year: Draco Malfoy. "This is Crabbe and Goyle, and I'm Malfoy. Draco Malfoy," Siwa mouths along to the character's iconic line from "Harry Potter and the Sorcerer's Stone" as she extends a hand toward the camera in an Instagram video posted on Wednesday. Selling us on the idea that polyjuice potion is real, Siwa also seemingly dyed her hair bleach blond and slicked it back in a perfect imitation of Tom Felton's 2001 costume.

From the hair to the button-up cardigan and tucked-in tie, every inch of Siwa's Draco Malfoy ensemble was perfection, but the best part of her costume was her commitment to impersonating the pretentious Slytherin. "Think my name's funny, do you?" she continues, glaring at the camera. "There's no need to ask yours. Red hair and a hand-me-down robe? You must be a Weasley." With a curl of her lip and a piercing stare toward the camera, there's no doubt that Draco Siwa's father will hear about this.

While she's been busy competing on "Dancing With the Stars" and making cameos on "High School Musical: The Musical: The Series" this year, we wouldn't be surprised if the "Kid in a Candy Store" singer unleashed her inner villain on stage in a live — possibly musical — production of the original Harry Potter films in the future.

Celebrities like Millie Bobby Brown, Vanessa Hudgens, Megan Thee Stallion, Jordan Fisher, and more have also been getting into the Halloween spirit this year, posting photos of costumes that range from cute to creepy to nostalgic. This look definitely has us feeling the latter.
