If you haven't seen it yet, Booksmart is about to be your new teen movie obsession. It stars Beanie Feldstein and Kaitlyn Dever, is directed by Olivia Wilde, and has 97% on Rotten Tomatoes, so get yourself to the cinema to see it ASAP.
Also, this is iconic pop queen Ms Taylor Alison Swift.
On Tuesday, one of the stars of Booksmart, Diana Silvers, posted a video of herself singing an altered version of Taylor's "Delicate" and asking her to go see the film.
Obviously, people stanned.
Including Taylor Swift, who posted the clip on her Instagram story, and said she just bought tickets to see the movie.
I'm pretty sure Kaitlyn Dever saw the story first, because she posted this video on Twitter thanking Taylor for the support.
THEN Diana posted this video on her Instagram story, literally kicking the air with excitement over the message from Taylor (which is a very big mood, TBH).
And then she tweeted the best — and most accurate — tweet.
YOU DON'T NEED BOYS WHEN YOU HAVE TAYLOR SWIFT.
Now everyone go see Booksmart! Goodbye!!!
