Ariana Grande has been steadily teasing her upcoming music video for "thank u, next" and all the movie references that she'll be adding into the video.Here's which movies we know about so far! Ariana will be paying homage to the 2000 cheerleading movie "Bring it On"! She'll also be playing Elle Woods from 2001's "Legally Blonde." She even got Jennifer Coolidge in on it, who was in the original film. Based on the caption for this one, it looks like there will be some "Mean Girls" (2004) references as well! Last but not least, a very subtle hint towards 2004's "13 Going on 30."
