Culpa Nuestra Shocker: Nicole Wallace and Gabriel Guevara Reportedly Caught Arguing on Set — Insiders Say This Was the Moment That “Completely Changed Their Relationship.” Fans Are Left Wondering: Was Their On-Screen Chemistry Ever Real?
In the glittering yet treacherous world of Hollywood romances—both fictional and otherwise—the line between on-screen passion and off-screen drama often blurs into a tantalizing haze. For fans of Prime Video’s blockbuster Culpables trilogy, that haze has thickened into a storm cloud with the release of the final installment, Culpa Nuestra (translated as Our Fault), on October 16, 2025. Starring the magnetic duo of Nicole Wallace as the fierce Noah and Gabriel Guevara as the brooding Nick, the film promises a heart-wrenching conclusion to their forbidden step-sibling love story. But as trailers rack up millions of views and streaming records shatter, whispers from the set have exploded into a full-blown scandal: a heated argument between Wallace and Guevara that insiders claim irrevocably altered their bond. Was this blowup the death knell for their once-unbreakable camaraderie? And more crucially, was the sizzling chemistry that captivated audiences in Culpa Mía (2023) and Culpa Tuya (2024) ever genuine, or just masterful method acting? As fans dissect every glance and gesture, the truth feels as elusive as the trilogy’s elusive happy ending.
To understand the shockwaves rippling through the fandom, we must rewind to the trilogy’s euphoric beginnings. Adapted from Mercedes Ron’s wildly popular Wattpad novels, the Culpables saga follows Noah, a resilient teen uprooted to a new life with her mother’s new husband and his enigmatic son, Nick. Their initial clash evolves into a scorching romance fraught with jealousy, betrayal, and high-stakes drama—think Romeo and Juliet with race cars and Riviera backdrops. When Culpa Mía (My Fault) dropped in June 2023, it became Prime Video’s most-watched non-English film globally, amassing over 60 million views in its first week. Much of that success hinged on Wallace and Guevara’s electric rapport. At 22 and 23 respectively during filming, the Spanish actors—Wallace with her breakout role in El secreto de Puente Viejo, Guevara fresh from Netflix’s Skam España—oozed youthful intensity. Behind-the-scenes clips showed them laughing during rehearsals, sharing inside jokes, and even vacationing together in Ibiza. Social media was ablaze with #NickAndNoahRealLife theories, fueled by cryptic posts: Wallace’s Instagram story of a sunset captioned “Racing hearts,” Guevara’s shirtless gym selfie tagged with her handle.
“From day one on Culpa Mía, their energy was infectious,” recalls director Oriol Paulo in a 2023 interview with Variety. “Nicole and Gabriel didn’t just play lovers; they lived it in the moment.” Fans ate it up, spawning fanfiction, edits set to Olivia Rodrigo tracks, and endless TikTok duets reenacting their steamy pool scene. By the 2023 press tour, the pair were inseparable: joint interviews where they’d finish each other’s sentences, red-carpet poses that screamed more than platonic, and a viral video of Guevara playfully carrying Wallace across a Madrid street. Whispers of a real-life romance swirled, with tabloids like Hola! speculating they were “Spain’s new power couple.” Neither confirmed nor denied, but their denials—”We’re just really good friends who understand each other deeply,” Wallace told Cosmopolitan—only fanned the flames.
Fast-forward to late 2023, and the cracks began to show. Filming for Culpa Tuya (Your Fault), the trilogy’s sophomore entry, kicked off amid high expectations. But insiders now reveal the set was a pressure cooker. Sources close to production, speaking anonymously to The Direct, describe a “toxic undercurrent” brewing from the start. “The long hours, the emotional toll of reliving Nick and Noah’s toxicity—it wore on them,” one crew member says. “What started as playful banter turned into real frustration.” Rumors of off-camera hookups persisted, but so did reports of jealousy: Guevara allegedly uncomfortable with Wallace’s growing fanbase, Wallace irked by Guevara’s flirtatious promo antics. Then came the unfollows. On November 1, 2023, Wallace quietly removed Guevara from her Instagram follows—a digital guillotine that sent shockwaves through stan Twitter. He reciprocated days later, scrubbing comments from her posts and deleting joint photos. “It felt like a breakup announcement without the announcement,” laments a fan in a viral X thread. Cue the cryptic posts: Wallace’s story of a lone wolf emoji, Guevara’s playlist addition of Taylor Swift’s “I Did Something Bad.”
The premiere of Culpa Tuya on December 27, 2024, turned speculation into spectacle. At Madrid’s Callao Cinema, the red carpet was a masterclass in avoidance. Wallace, radiant in a crimson gown, arrived solo and stuck to author Mercedes Ron like glue. When photographers clamored for a Nick-and-Noah pose, she demurred, later caught on video excusing herself from the stage mid-event as Guevara approached. No eye contact, no small talk—just icy politeness. TikToks exploded: “From BFFs to this? What did he DO?” racked up 5 million views. Spanish outlet Los40 dubbed it “the tension you could cut with a knife,” noting Wallace’s refusal to even feign a smile for solo shots with her co-star. Guevara, ever the charmer, downplayed it in interviews: “We’re professionals; the work speaks for itself.” But fans weren’t buying it. Theories proliferated: Was it a lovers’ quarrel gone nuclear? Did Guevara’s new girlfriend, actress María de Nati—publicly confirmed in early 2024—draw battle lines? (De Nati and Guevara were spotted kissing at a Valencia film fest, mere weeks after the unfollow saga.) Or was it simpler—burnout from embodying a couple whose every arc was engineered for angst?
Enter the shocker: the on-set argument that’s now being hailed as the “relationship death knell.” According to multiple eyewitness accounts leaked via X threads and corroborated by entertainment blogs, the blowup occurred during Culpa Tuya‘s final weeks of production in early 2024. “It was a screaming match—raw, unfiltered,” dishes an insider to FandomWire. The trigger? A heated rehearsal for a pivotal confrontation scene, where Nick accuses Noah of betrayal. Fiction bled into reality: Wallace reportedly called out Guevara for “always making it about you,” while he fired back that she was “impossible, just like always.” Voices escalated; crew froze. Guevara stormed off set, production halting as a coordinator chased him down. “The director had to intervene—separate them, reset the scene,” the source adds. “From that moment, it was like a switch flipped. No more laughs, no more lingering hugs between takes. Their dynamic? Completely changed.”
X user @m_r_r0601, who claims ties to the production, detailed the fallout in a now-infamous thread: “Gabriel was telling Nicole it was always the same with her—frustrations bubbling over months of intensity.” Another post alleges body-shaming undertones, with Guevara liking memes mocking Wallace’s figure post-filming—claims he denies through reps. Wallace, in a rare Cosmopolitan sit-down for Culpa Nuestra promo, addressed the elephant: “We’ve shared so much—triumphs, challenges. But growth means setting boundaries.” Guevara echoed maturity in his own chat: “Noah’s empowered; she pushes you to be better. Off-screen? We’ve evolved too.” Yet, a recent promo video for Culpa Nuestra—the pair reading fan letters stiffly from cue cards—has only reignited doubts. “They look like strangers,” one viewer commented, amassing 10K likes.
So, was the chemistry ever real? Die-hards point to Culpa Mía‘s authenticity: unscripted ad-libs, genuine tears in emotional takes. “You can’t fake that spark,” argues film critic Elena Ruiz in El País. But skeptics, peering through the feud’s lens, see smoke and mirrors. Culpa Tuya grossed even higher—80 million views—despite the rift, suggesting professionalism trumped personal beef. Culpa Nuestra, directed by Domingo González, leans into maturity: a time-jump arc where Nick and Noah confront adult realities, including new relationships. Wallace’s Noah is “newfound fierce,” per reviews, while Guevara’s Nick simmers with “quiet vulnerability.” Early buzz calls it the trilogy’s strongest, with an IMDb 5.3 buoyed by their “nuanced” performances. Yet, one X user nails the fan psyche: “If they hated each other and still delivered this fire, imagine if they’d loved it?”
The feud’s ripple effects? Box-office gold. Culpa Nuestra‘s trailer broke records pre-release, curiosity spiking amid the drama. English remakes like My Fault: London are greenlit, proving the IP’s Teflon resilience. For Wallace and Guevara, it’s a double-edged sword. She’s thriving solo—headlining a Netflix thriller next year—while he juggles Culpa residuals with De Nati dates. But the scars linger: no joint posts, no reunion teases. Fans, heartbroken yet hooked, flood X with pleas: #ReuniteNickAndNoahIRL trends sporadically, blending pleas for reconciliation with memes of their red-carpet freeze-out.
In the end, Culpa Nuestra isn’t just a finale; it’s a meta-commentary on love’s fault lines—passion that ignites, then incinerates. Whether Wallace and Guevara’s bond was ever more than collegial alchemy may forever remain off-limits, a private script we’ll never read. But as Noah and Nick race toward closure on screen, fans can’t help but wonder: in the rearview, was any of it real? Or was it all just another twist in the Culpables game? One thing’s certain—their story, fractured as it is, has us revved up for more.
