Is this the end… or the steamiest twist yet? Hearts are breaking, jaws are dropping. Dive into the exclusive teaser that has everyone spiraling—click here to watch before it vanishes! 👉

In a move that’s sending shockwaves through the fandom, Prime Video dropped a jaw-dropping teaser trailer for what appears to be The Summer I Turned Pretty Season 4 on Thursday, igniting speculation that the sun-soaked romance saga isn’t quite ready to fade into the sunset. Just weeks after the emotional rollercoaster of Season 3’s finale on September 17, which wrapped up Jenny Han’s beloved trilogy with Belly Conklin (Lola Tung) finally choosing Conrad Fisher (Christopher Briney) in a tear-soaked Paris reunion, the streaming giant is hinting at fresh drama that veers wildly from the source material. Titled “A New Beginning,” the 90-second clip teases a time-jump forward, where a grown-up Belly navigates motherhood, heartbreak, and an unexpected crossroads with ex Jeremiah Fisher (Gavin Casalegno). Fans are already divided: Is this a bold extension of Han’s universe, or a desperate cash-grab on a story that ended oh-so-perfectly?

The trailer opens with sweeping drone shots of Cousins Beach at dawn, the golden sands now dotted with seashells and a child’s tiny footprints—a subtle nod to the new life about to upend everything. Cut to Belly, now in her mid-20s, cradling a newborn in a sun-drenched nursery overlooking the ocean. “Some summers change you forever,” she narrates in a husky, world-weary voice, her signature wavy hair tousled and eyes shadowed by something deeper than jet lag. The baby—rumored to be the result of a whirlwind post-finale romance—gurgles softly as Belly whispers, “You’re my everything now.” But the idyll shatters quickly: a montage flashes of late-night feedings, crumpled love letters, and Belly staring at an old photo of the Fisher brothers, her face a mask of quiet devastation.

Enter Jeremiah, whose arc in the teaser feels like a gut punch to Team Jere diehards. No longer the carefree golden boy chef from Season 3’s epilogue—where he was last seen flirting with new flame Denise (Isabella Briggs) in a Boston bistro—the trailer shows him gaunt, unshaven, and staring down a life-altering decision. In a dimly lit bar overlooking the Atlantic, he downs a whiskey and mutters to a shadowy figure (possibly his father, Adam, played by Jack Holden), “I walked away once. I won’t do it again.” Flashbacks intercut: Jeremiah at Belly’s hospital bedside during labor, his hand hovering over hers before pulling back; a heated argument where he demands, “You chose him, Belly. But this? This changes nothing?” The clip culminates in a rain-soaked beach confrontation, Jeremiah on one knee—not with a ring, but holding the baby’s ultrasound photo, pleading, “Let me be the father you need me to be.” Is he claiming paternity? Stepping up as a platonic co-parent? Or reigniting the flames that nearly destroyed the brothers’ bond? The ambiguity is deliciously cruel, leaving viewers to scroll X (formerly Twitter) in a frenzy of theories.

This isn’t just fan service; it’s a narrative grenade lobbed into the heart of Han’s meticulously crafted world. For the uninitiated, The Summer I Turned Pretty—adapted from Han’s 2009-2011 YA trilogy—chronicles Isabel “Belly” Conklin’s evolution from awkward teen to empowered young woman, entangled in a love triangle with the brooding Conrad and his sunny sibling Jeremiah. Season 1 (2022) introduced the Cousins Beach magic, with Belly’s first kiss and Susannah Fisher’s (Elaine Hendrx) terminal illness casting a pall over the volleyball games and bonfires. Season 2 (2023) ramped up the angst, as Belly’s engagement to Jeremiah crumbles amid betrayals and grief, culminating in a gut-wrenching choice that echoed the second book’s feverish pitch. Season 3, the supposed swan song announced as final in March 2025, premiered July 16 with an 11-episode arc that drew 25 million global viewers in its first week, per Prime Video metrics. It adapted We’ll Always Have Summer, where Belly and Jeremiah’s college-era romance frays under infidelity rumors (Jeremiah’s one-night stand in the books, amplified to two in the show for extra sting), only for Conrad to swoop in with a late-night confession that seals their fate.

The finale, “All Roads Lead to Paris,” was a masterclass in catharsis: Belly, now 22 and studying abroad, celebrates her birthday at a Eiffel Tower café when Conrad crashes the party, fresh from med school in California. Their reunion—kissing under twinkling lights as Taylor Swift’s “Daylight” swells—is the payoff Team Conrad fans had clamored for since 2022. Jeremiah, meanwhile, gets a bittersweet bow: thriving as a chef but haunted, toasting alone to “the one that got away.” Showrunner Jenny Han, in a post-finale Variety interview, defended the ending as “true to the books’ spirit,” emphasizing Belly’s growth into self-assured adulthood. “Three books, three seasons,” she told Entertainment Weekly earlier this year. “It feels right.” Yet, whispers of expansion lingered—Han teased a potential feature film in August 2023, greenlit on finale day to “conclude the story” with her penning the script alongside co-showrunner Sarah Kucserka.

So, how does a baby fit? Insiders close to production (speaking anonymously to this outlet) reveal the Season 4 pitch emerged during Season 3 reshoots in April 2025, after Han’s “never say never” comments in a USA Today profile sparked viral buzz. The teaser, filmed in secret on the original Wilmington, North Carolina sets, jumps five years ahead: Belly, 27, is a single mom post a brief, unnamed relationship (speculation points to a European fling during her Paris sabbatical). The child’s father? Deliberately vague, but Jeremiah’s “decision” teases a custody battle or surprise paternity reveal, forcing the exes to co-parent amid Conrad’s stable-but-stifling doctor life in Boston. “It’s about legacies,” Han hinted in a cryptic X post last week, quote-tweeting fan art of a toddler in a Cousins Beach onesie. “What we inherit, what we build, what we let go.”

The cast’s return adds layers of intrigue. Lola Tung, 26, embodies a more maternal Belly, trading crop tops for flowy sundresses while retaining that fiery spark—her chemistry with Briney crackles in a quick cut of them arguing over baby names. Gavin Casalegno, 25, steals the show as a matured Jeremiah: tattooed sleeves peeking from chef whites, eyes rimmed with regret. “Jeremiah’s always been the heart,” Casalegno told Refinery29 post-finale. “This season, he fights for his piece of it.” Newcomers include Kristen Connolly as Belly’s no-nonsense OBGYN mentor (recurring from Season 3) and Tanner Zagarino as Jeremiah’s frat-bro confidant, bringing comic relief to the baby chaos. Returning vets like Rain Spencer (Taylor) and Sean Kaufman (Steven) pop up in group texts about “auntie duties,” while Jackie Chung’s Laurel offers wry advice on blending families.

Critics and fans are split down the middle. On Rotten Tomatoes, Season 3 holds a solid 82% (up from Season 2’s 74%), praised for elevating the books’ melodrama with Swift Easter eggs and diverse casting expansions—like Sofia Bryant’s Anika as Belly’s queer roommate exploring fluid identities. But purists decry the baby plot as “fanfic gone wild,” arguing it cheapens Belly’s hard-won independence. “The books ended with hope, not diapers,” tweeted one X user, amassing 3K likes. Others celebrate the maturity: “Finally, real stakes beyond prom drama,” posted a Team Jeremiah stan, referencing Casalegno’s emotional bar scene. Viewership data backs the hype—Season 3’s Paris episode spiked 40% in 18-34 female demos, per Nielsen, with global acquisitions topping Prime’s charts.

Behind the scenes, production hurdles were no small feat. Filming kicked off in secrecy July 20, mere days after the finale’s wrap party, dodging paparazzi with NDAs thicker than a Cousins fog bank. Director Jesse Peretz (Season 1 alum) returned for the teaser, infusing it with Han’s signature nostalgia—think slow-mo waves crashing over a spilled baby bottle. Budget whispers peg it at $12 million per episode, up 20% from Season 3, thanks to international shoots in France and expanded VFX for dream sequences where young Belly ghosts the adults, whispering regrets. Tung, fresh off a 2024 indie darling The Perfect Find, relished the pivot: “Belly’s not just the girl next door anymore—she’s a force.” Briney, balancing med school research for authenticity, added, “Conrad learns vulnerability isn’t weakness; it’s survival.”

As for the “new beginning” hook, it ties neatly to Han’s evolving oeuvre. The author, whose To All the Boys franchise minted Netflix gold, has long toyed with sequels—her 2025 EW sit-down floated a “decades later” spin-off, echoing Burn for Burn‘s ghost-story vibes. The Season 4 greenlight, confirmed via Prime’s investor call last month, aligns with Amazon’s YA push amid strikes’ aftermath, banking on the show’s 100M+ hours watched. Yet, Han insists it’s organic: “Stories don’t end; they ripple.” The teaser closes on Belly rocking the baby to sleep, Conrad’s shadow in the doorway, and Jeremiah’s truck peeling away—tagline: “Some loves return with the tide.”

Will Season 4 premiere summer 2026, as rumored? Prime’s mum, but with a writers’ room already buzzing and Swift on speed-dial for the soundtrack, bets are on a July drop. For now, the fandom’s ablaze: X threads dissect every frame, from the baby’s non-newborn chubby cheeks (practical effects, per leaks) to Jeremiah’s “redemption arc” potential. Love it or loathe it, this twist cements The Summer I Turned Pretty as more than beach reads—it’s a mirror for messy, enduring hearts. As Belly says in the books, “The ache will always be there.” But hey, at least now there’s a lullaby for it.
