Prime Video Unveils Final Trailer for “The Summer I Turned Pretty” Season 3

August 29, 2025 - Prime Video surprised fans today by releasing the official trailer for the final three episodes of its hit YA drama The Summer I Turned Pretty Season 3. The teaser drops Belly (Lola Tung) into an unexpected new chapter in Paris, offering viewers a first glimpse of both her adventures abroad and the emotional stakes awaiting the series’ conclusion.

In the two-minute trailer, Belly boards a plane to Paris after calling off her wedding to Jeremiah (Gavin Casalegno), confessing, “I had these pillars in my life-Cousins, my family, Taylor, Jere. Now they’re gone. And it’s just me.” As she forges new friendships and explores life in the City of Light, a surprising letter from Conrad (Christopher Briney) interrupts her fresh start. The trailer closes on Conrad’s voiceover: “Dear Belly…,” teasing unresolved tensions and promising that “anything could happen” in the home stretch.

Prime Video also revealed four new recurring cast members who will join Belly’s Parisian journey:

• Corinna Brown (Heartstopper)
• Fernando Cattori (With You in the Future, Untamed Royals)
• Isaline Prevost Radeff (Ceux Qui Travaillent, Haute Mer)
• Jahz Armando (Gangs of London)

The final three episodes begin streaming Wednesday, September 3, with the series finale set for September 17. Fans are bracing for a conclusion that may deviate from Jenny Han’s bestselling source material, as the showrunner hinted that Belly’s ultimate choice between Conrad and Jeremiah might remain open-ended.
