Throughout season 3 of The Summer I Turned Pretty, fans have been quick to spot all of the Taylor Swift references that could hint at who exactly Belly ends up with at the end of the series.

But Jenny Han’s latest easter egg has sent fans into a frenzy.

On Aug. 4, the showrunner and author shared a behind-the-scenes moment with actress Lola Tung on TikTok.

The actress who plays Belly in the show was filming the scene with Swift’s “All Too Well” playing in the background.

In the caption, Han revealed that “All Too Well” was the the track she “had playing for Lola during this scene” from episode 2. @jennyhan
