Warning: Major Taylor Swift spoilers below if you haven't seen "Cats."

If you are a Taylor Swift fan who has already gone to see "Cats," you know the awful truth: she's doesn't have much screen time.

That probably shocked you, since from the trailer and other marketing for the movie, it seemed like the superstar had a meaty role like Jennifer Hudson, Rebel Wilson, and Idris Elba. In actuality, she has the least screen time of any of the stars.

Swift's big moment comes toward the end of the movie when she sings the seductive "Macavity" number (in a British accent) and sprinkles catnip all over the Jellicles.

Yep, that's it. It's pretty much what you saw in the trailer. That's her screen time in the movie.

However, there is one other very brief moment. When Macavity (played by Idris Elba) takes her character, Bombalurina, with him to prevent the choosing of a cat for the Heaviside Layer (don't worry if none of this makes sense, I've seen the movie and had no clue what the heck was going on).

It's implied that Macavity and Bombalurina are now teaming up to stop the annual ritual. But only Macavity appears, and is too late to stop it. What happened to Swift's Bombalurina?

"I suppose I feel like in the end he's selfish enough that the glory will be only for him," "Cats" director Tom Hooper told Insider. "It's, 'come with me,' but it's really all about him. He's that kind of villain."

And for those fans hoping that maybe in the future more TSwift footage that was discarded will be revealed, don't hold your breath for a #TaylorSwiftCut. Hooper said what you see in the movie is what they shot of Swift.

It seems Swift was more involved behind the scenes. She teamed with Andrew Lloyd Webber, who composed all the iconic "Cats" songs, to write a new song for the movie, "Beautiful Ghosts." Judi Dench performs a scaled-down version of it in the movie and Swift sings the song in the end credits.
