Amazon’s coming-of-age drama "The Summer I Turned Pretty" marked the debut of its third and final season with a red-carpet premiere in New York on 16 July 2025. Principal cast members Lola Tung, Gavin Casalegno and Christopher Briney headlined the launch, joined by co-stars Rain Spencer and Sean Kaufman. The actors posed for photographs and reflected on closing out the series, which has followed teenager Belly Conklin’s coastal summers since its 2022 debut. Later the same evening, Tung, Casalegno and Briney taped an appearance on NBC’s "The Tonight Show Starring Jimmy Fallon," where they discussed filming the season well in advance and the emotions of wrapping the storyline.
