After much anticipation, Ariana Grande finally dropped her music video for "Thank U, Next," and it's full of celebrity cameos (15, to be exact). Given that the video pays homage to our favourite rom-coms from the early 2000s — Legally Blonde, Mean Girls, 13 Going on 30, and Bring It On — it makes sense that Ariana tapped some of the characters from the films. Yep, we're talking about Jennifer Coolidge and Jonathan Bennett! Not to mention, Kris Jenner also makes a hilarious appearance. See all the cameos you might have missed ahead.
