"I can't thank you enough for wanting to see this film that so vividly captures my favorite adventure I've ever been a part of: The Eras Tour. And the best part is, it's an adventure we're still on together," Swift wrote.

As for her outfit, the Anti-Hero artist paid homage to her next re-recording, 1989 (Taylor's Version), with a light blue gown and pinned-up hair, replicating her signature bob from the era.

But Swift's "actual fairytale" of an evening only got more exciting with the arrival of Beyoncé, who showed her support with a surprise appearance at the premiere.

Swift personally thanked Beyoncé for attending the premiere with an Instagram post featuring a video of the pair sitting in the theater together.

"I'm so glad I'll never know what my life would've been like without @beyonce's influence," the Karma songstress wrote.

"She's been a guiding light throughout my career and the fact that she showed up tonight was like an actual fairytale," she added.

Bey's record-breaking Renaissance World Tour is set to get its own moment on the big screen with a concert film premiering on December 1.
