Ariana Grande Does Epic Jennifer Coolidge ‘Best In Show’ Halloween Transformation

Ariana Grande and Liz Gillies have won Halloween! On Friday, the besties proved to be quite the dynamic duo on Instagram, when they showed off their top-notch impersonation skills for an uncanny reenactment of the 2000 mockumentary film “Best in Show.” The former “Victorious” co-stars dressed up as several characters from movie for Halloween, although they might have prepared the bit some time ago. “Happy Halloween. We did this in May,” they wrote in their shared post.
