Kourtney Kardashian as Ariana Grande will certainly make you do a double take. Among her many costumes this year, the 39-year-old reality TV star channeled the 25-year-old pop star by recreating the same look Grande wore during an appearance on The Tonight Show With Jimmy Fallon in May. In addition to wearing a similar pink minidress and thigh-high boots, Kardashian nailed Grande's signature hair and makeup.
Neutral lip? Check. Dramatic cat eye? Check. Edgy hair accessories? Check. Sky-high ponytail? Oh, you better believe it. Not only that, but Kardashian took the ponytail to the next level by crimping it, which gives it a little extra pop-star flair. The costume was quickly noticed by Grande, who commented a string of black hearts on Kardashian's post. See pictures of the sweet tribute ahead.
