Ariana Grande channels her inner Regina George in the 'Mean Girls' themed video for her latest single 'thank u, next'. In it she likens the madness of fame to high school popularity, and it's so fetch. It even features some of the stars from the original including Jonathan Bennett, Stefanie Drummond and Jan Caruana. She also pays tribute to 'Bring it On' with the movie's own Matt Bennett, as well as Legally Blonde with Jennifer Coolidge. The video also stars Miranda Sings, Kris Jenner, Troye Sivan and the cast of 'Victorious'.
