In season three, Belly and Jeremiah are seen as a couple at Finch University, where they study together. The romantic scenes on campus are accompanied by Taylor Swift's music, including Daylight and Red (Taylor's Version).
Also returning in season three are Sean Kaufman as Belly’s older brother Steven, Rain Spencer as Belly’s best friend Taylor Jewell, and Jackie Chung as Belly’s mother Laurel. One of the episodes will also be directed by author Jenny Han herself.
The full trailer gives us a sneak peek at a key moment from the book We’ll Always Have Summer – namely, Belly and Jeremiah’s wedding. However, this announcement causes doubts for Belly’s mother Laurel. Meanwhile, Conrad remains a defining presence, which causes tensions, including during a scene in which he unexpectedly walks into the summer house – while Swift’s Red (Taylor’s Version) plays in the background.
Season three consists of eleven episodes, an expansion from the previous seasons. The series starts on Wednesday, July 16 with two episodes immediately. After that, a new episode will follow weekly on Wednesdays, with the finale on September 17, 2025.
The Summer I Turned Pretty season three promises to be an emotionally, musically and visually powerful conclusion to Belly’s journey. Prime Video is opting for a hybrid rollout with weekly episodes, gradually building the suspense until the big finale on September 17. Fans can expect love, heartbreak and – maybe – a wedding.
