We're dying over Ariana Grande's Jennifer Coolidge costume

We knew she's a fan of The White Lotus star, but this Ariana Grande Halloween costume seals her Jennifer Coolidge stan-dom. 

The "Dangerous Woman" singer has famously impersonated Coolidge's signature breathy voice in the past, a loving imitation that led to a cameo in the singer's "Thank U, Next" music video. Now the pop star is paying homage to one of the Emmy winner's most beloved film roles: trophy wife Sherri Ann Cabot in the 2000 mockumentary Best in Show. 

Longtime friends and former Victorious co-stars, Grande and Liz Gillies showed off their Best in Show get-ups on Instagram on Friday, October 28, with the former as Coolidge's character and the latter portraying Jane Lynch's Christy Cummings. They then switched it up, with Grande as Eugene Levy's bold-browed Gerry Fleck and Gillies as Catherine O’Hara’s curly-haired Cookie Fleck. 

Not only did the actresses take on the look of the cult-favorite characters but also, epically, their mannerisms, recreating some of the funniest scenes from the Christopher Guest classic. Watch the dynamic duo below:

Coolidge herself praised the performers, commenting on the post: "This is f***ing great. I was gonna go as the young boy’s pet weasel from 'The Watcher' but now I think I’m gonna go as @arianagrande’s dog Toulouse 😉"

Other celebrities also joined in with virtual applause, including Katy Perry, who wrote: "can this get nominated." We couldn't agree more!
