Will The Summer I Turned Pretty movie be a Christmas movie?

Outside of one-off episodes and flashbacks, The Summer I Turned Pretty is famous for being set in summer. Not only that but every season has been released in summer. That being said, two fan favourite scenes are set at Christmas time - Belly and Conrad's cocoa scene in season 2 and Belly and Conrad's Christmas scene in season 3.

As a result, viewers have found it intriguing that The Summer I Turned Pretty season 3 ends with a photo montage of Belly and Conrad spending "Christmas in Paris". The photographs show Belly and Conrad snuggling in Belly's Paris flat as Darlene Love's 'Christmas (Baby Please Come Home)' plays.

Christmas obviously means a lot to Belly and Conrad but the montage comes a bit out of the blue. With this in mind, people are convinced that the photo montage is an easter egg hinting that The Summer I Turned Pretty will be a Christmas movie.

Reacting, a fan tweeted: "Guys walk with me here.. what if we get a summer I turned pretty Christmas movie next year?" Another said: "The Summer I Turned Pretty The Christmas Movie would be epic".

If so, Belly and Conrad could get engaged and maybe even married at Christmas!

In a viral TikTok, another fan pointed out that the bumber 14 features multiple times in the episode. They wrote: "we kept seeing 14. the movie will come out in 14 weeks. 14 weeks from today's show is christmas DAY. that's why the end credits was a christmas photoshoot."

The video has since been viewed over 500,000 times. In the comments, one fan wrote: "I BEG ITS AN XMAS FILM that we can watch every year." Another said: "The Christmas I got married??"

As it stands, plot details for The Summer I Turned Pretty movie are yet to be confirmed but Jenny's statement about "another big milestone left in Belly’s journey" appears to reference her wedding to Conrad that features in a flash-forward at the end of the books.

According to Jenny, the movie is only in draft stages and yet to be filmed but, if production starts soon, it's possible we could get the film as soon as Christmas 2026. Could we see Belly and Conrad's engagement and wedding in a Christmas film?

What do you think? Will the movie be set at Christmas?
