Here's Ariana's mega-hyped cameo and cross-over heavy music vid for 'thank, u next'

It was already the biggest song in the world, but you can expect Ariana Grande's 'thank u, next' to be a whole lot bigger now. 

Overnight the much hyped music video premiered and there are a lot of pop culture references to unpack in this one.  

Those movie references are Mean Girls, Bring It On, Suddenly 30 (Called 13 Going On 30 overseas) and Legally Blonde.

As for cameos, keep an eye out for Kris Jenner, Jennifer Coolidge, the original Mean Girls love interest Jonathan Berret, and three of Ariana's old castmates in Victorious.
