‘The Summer I Turned Pretty’ Season 3 Trailer Sees Lola Tung’s Belly Getting Married (2025)

It’s not summer without your favorite love triangle.

After a summer off, the drama is back in the season three trailer for The Summer I Turned Pretty, starring Lola Tung, Gavin Casalegno and Christopher Briney, which Prime Video dropped Wednesday.

In the footage, Tung’s Belly and Casalegno’s Jeremiah announce that they’re getting married, to everyone’s surprise. However, when Briney’s Conrad returns and realizes he still has feelings for Belly, plans appear to get complicated.

“When I’m with Jere, everything is easier, but everywhere I go, there’s a memory of Conrad,” Tung’s Belly says in the trailer (below), set to Taylor Swift’s “Daylight” and “Red (Taylor’s Version).” “Life’s too short not to spend it with the person that you love.”

“It’s the end of her junior year of college, and Belly’s looking forward to another summer in Cousins with her soulmate, Jeremiah. Her future seems set, until some core-shaking events bring her first love Conrad back into her life. Now on the brink of adulthood, Belly finds herself at a crossroads and must decide which brother has her heart. Summer will never be the same…” the show’s season three logline reads.

This season also stars Sean Kaufman, Rain Spencer, Jackie Chung and Colin Ferguson.

Season three is helmed by showrunners Jenny Han and Sarah Kucserka, with both also serving as executive producers alongside Karen Rosenfelt, as well as Paul Lee, Hope Hartman and Mads Hansen of Wiip.

The Summer I Turned Pretty‘s third and final season, based on Han’s best-selling book trilogy of the same name, debuts on Prime Video on July 16.
