Life moves pretty fast in Taylor Swift’s world. In fact, she’s just revealed that she wrote, recorded and produced I Knew It, I Knew You – her new end credits song for Toy Story 5 – on the same day that she watched an early cut of the movie itself.

In a video posted on Instagram that was captured on the day in question, we see Swift addressing the camera. “Kind of a hectic day,” she begins. “At 11am, went to see Toy Story 5. Got so inspired, got the songwriter zoomies. Went home, wrote the end credits song for Toy Story 5. We have now produced it and I’m doing vocals. It’s 6.57pm.”
