Taylor Swift‘s mother filmed her being a bit delirious in the aftermath of eye surgery, and then… sent it to Jimmy Fallon without telling her.

That’s the official line anyway, and it’s hard to tell sometimes how set-up these chat show skits are, but the look on Taylor’s face as she realises what’s going on? Priceless. She’s horrified. Fuming!

The footage sees her taking bananas very, very seriously, and it’s… weirdly engrossing??

Oh, and in this interview – which aired last night – she also reveals that she’ll be performing Lover and one song that she hasn’t performed before when she does Saturday Night Live this weekend.

I’M JUST SAYING, I don’t think she’s done Cruel Summer live yet. JUST SAYING.
