Heated Rehearsal: Nicole Wallace and Gabriel Guevara’s Fiery Clash on Set Ends in Laughter—But Fans See Shadows of Deeper Tension

In the high-stakes pressure cooker of a film set, where emotions run as raw as the scripted drama, actors Nicole Wallace and Gabriel Guevara have mastered the art of blurring lines between performance and reality. As the stars of Prime Video’s blockbuster Culpables trilogy—adapting Mercedes Ron’s steamy Wattpad novels into cinematic gold—their portrayals of the volatile stepsiblings Noah and Nick have kept millions hooked on a rollercoaster of forbidden passion and heartbreak. My Fault (2023) ignited the fire, Your Fault (2024) fanned the flames, and now, with Their Fault (Culpa Nuestra, 2025) wrapping up the saga, whispers from the production have reignited scrutiny on their off-screen dynamic. Sources close to the set reveal a “heated rehearsal” where Wallace and Guevara locked horns over a pivotal scene for a staggering 30 minutes, voices raised in frustration before dissolving into shared laughter. Crew members describe it as a cathartic release, but fans—ever vigilant—see it as a window into lingering tension, especially with Guevara’s girlfriend, María de Nati, reportedly staying out of the spotlight during the film’s turbulent shoot.

The clash reportedly unfolded during reshoots for Culpa Nuestra in early 2025, amid the trilogy’s climactic exploration of Noah and Nick’s fractured reconciliation. According to anonymous crew accounts leaked to Spanish tabloid Hola! and amplified on fan-driven X threads, the argument erupted over a tense bedroom confrontation scene—mirroring the characters’ explosive push-pull of love and resentment. “Nicole wanted more vulnerability in Noah’s delivery, raw and unfiltered, while Gabriel pushed for Nick’s defensiveness to hit harder, with sharper edges,” one source detailed in a viral post that garnered over 10,000 likes. What began as a polite debate escalated into a full-throated 30-minute standoff, with raised voices echoing across the Madrid soundstage. “It was intense—hands gesturing wildly, scripts slapped down on the table,” the insider continued. “The director stepped in twice, but they were both so invested, it felt personal.” Yet, in a twist straight out of their rom-drama playbook, the tension shattered into peals of laughter when Wallace, mid-rant, tripped over a prop cable and pulled Guevara down with her. “They ended up in a heap, cracking up like old friends,” the crew member added. “It broke the ice, and the take they got right after? Magic.”

Grainy behind-the-scenes footage, smuggled out via a production assistant’s TikTok, captures the tail end: Wallace wiping tears of mirth from her eyes, Guevara playfully shoving her shoulder as they reset for the camera. The clip exploded on X, racking up 500,000 views in days, with users dubbing it “#RehearsalRealness.” “This is peak Nicogab—fight like enemies, laugh like lovers,” one commenter gushed, while another speculated, “30 minutes? That’s not acting frustration; that’s unresolved beef.” The moment’s levity contrasts sharply with the duo’s documented history of friction, turning what could have been a forgettable set anecdote into fodder for endless speculation.

To grasp the weight of this “heated rehearsal,” one must trace the fault lines in Wallace and Guevara’s real-life rapport. The pair’s journey began in 2023 with My Fault, a surprise smash that amassed 100 million viewing hours on Prime Video in its first week. Their chemistry was undeniable: promotional clips showed them giggling through interviews, finishing sentences, and sharing conspiratorial glances that had fans shipping #Nicogab harder than the on-screen duo. “We clicked instantly—it’s like we’d known each other forever,” Wallace told EL PAÍS in a June 2023 profile, her arm slung casually around Guevara’s shoulders. Guevara, echoing the sentiment, posted Instagram Stories of them rehearsing dance moves for a party scene, captioned “Chaos partners in crime.”

But cracks surfaced by late 2023. Wallace unfollowed Guevara on Instagram on November 1, coinciding with a cryptic Story of her blasting Olivia Rodrigo’s “Traitor.” Fan sleuths connected dots to Guevara’s Venice Film Festival controversy—a brief detention over unproven assault allegations from his youth, quickly cleared—and rumors of him liking shady comments about Wallace’s appearance. By the Your Fault premiere in December 2024, the chill was arctic: Wallace bolted from a joint photo op, avoiding eye contact on the red carpet, while Guevara arrived solo, his jaw set. “It was awkward as hell— like watching your parents at Thanksgiving after a divorce,” tweeted a attendee, a post that spiraled into 20,000 retweets. Insiders whispered of jealousy over Guevara’s budding romance with de Nati, a poised 29-year-old actress from La Mesías, whom he confirmed dating in early 2024. “María’s presence changed things—Gabriel pulled back from the fan service,” a mutual friend allegedly confided to FandomWire.

Enter Culpa Nuestra, filmed back-to-back with Your Fault but released October 16, 2025, to 150 million streams in its debut week—shattering trilogy records amid feud-fueled hype. The script demanded maturity: a time-jumped Noah and Nick navigating adulthood’s scars, with scenes of blistering arguments that tested the actors’ mettle. “We had to dig deep—channel our own frustrations to make it authentic,” Guevara admitted in a GQ España interview, though he dodged specifics on their dynamic. Wallace, more candid in Collider, reflected: “Noah’s growth mirrored mine—learning to fight fair, then forgive.” Yet, set reports paint a picture of intermittent ice: separate trailers, mediated script reads, and that now-infamous rehearsal blowout.

Fans, a global army of 2 million-plus across TikTok and X, have turned the incident into a Rorschach test for their theories. On Reddit’s r/Culpables, a megathread titled “The 30-Min Fight: Makeup or Breakdown?” amassed 5,000 upvotes, dissecting the video frame-by-frame: “Look at her shoulders—tense until the fall. That’s real anger, not play.” Shippers romanticize it as “tension turning to passion,” editing the clip to Ed Sheeran’s “Photograph” with captions like “They argue because they care too much.” Detractors, however, point to de Nati’s conspicuous absence. Spotted at Culpa Tuya‘s afterparty but skipping Nuestra‘s Ibiza retreat, the actress has maintained radio silence on the drama, focusing on her theater run in Barcelona. “María’s in the shadows because she’s tired of being the villain in fanfics,” speculated a X user in a thread with 15,000 engagements, linking pap shots of her and Guevara vacationing post-wrap. De Nati’s subtle IG nod—a heart emoji on Guevara’s wrap post—fueled counters: “She’s secure; it’s Nicole who’s salty about being sidelined.”

The girlfriend’s “shadowy” role adds layers to the narrative. De Nati, Guevara’s rock through his 2023 scandal, has been painted as the catalyst for the rift—jealous of Wallace’s spotlight or enforcing boundaries amid shipping frenzy. “Gabriel’s happy with María; the laughs are just professional thawing,” defended a source in a YouTube exposé that hit 2 million views. Yet, X sleuths unearthed deleted comments from Guevara’s account liking anti-ship memes, and a leaked text purportedly from de Nati urging “distance for peace.” Fans are split: #TeamMaria posts celebrate her poise (“Queen staying above the mess”), while #JusticeForNicogab rallies cry foul (“Let them heal—30 minutes of fight means 30 years of what-ifs”). One viral edit mashes the rehearsal clip with Culpa Nuestra‘s trailer fight scene, caption: “Art imitating the mess they won’t admit.”

Professionally, the duo shines. Culpa Nuestra earned praise for their nuanced turns—Wallace’s tearful monologues lauded as “career-best” by Variety, Guevara’s brooding restraint called “magnetic” by IndieWire. Promos showed forced smiles: a split-screen interview where Wallace dominates, Guevara fidgeting; a fan Q&A where they read letters but dodge joint anecdotes. “We’re pros—tension fuels the work,” Wallace quipped to ELLE, eyes flicking away from the camera. Guevara, in a solo Variety sit-down, added: “Arguments on set? Part of the job. Laughter’s the best reset.” But body language experts on TikTok beg to differ: “His lean-ins scream unresolved; her laughs feel guarded.”

This isn’t just gossip—it’s symptomatic of shipping’s dark side. The Culpables fandom, while creative (fanfics topping AO3 charts), has hurled vitriol: Wallace deluged with “homewrecker” DMs, Guevara branded “player.” De Nati’s low profile? Likely self-preservation; a 2025 Guardian piece on celeb couples notes “girlfriends of co-stars often vanish to avoid the mob.” As Culpa Nuestra streams to acclaim—praised for its “mature twist” on young love—fans grapple with the irony: a film about forgiveness, starring actors who might need it most.

Wallace, 23, eyes a Netflix thriller next, hinting at “fresh starts.” Guevara, 24, teases indie fare with de Nati. Their 30-minute storm, ending in giggles, whispers of healing—or just another layer in the saga. As one X poet put it: “They argue like Nick and Noah, laugh like survivors. But with her in the wings, who’s the real fault?” In Hollywood’s echo chamber, where rehearsals bleed into rumors, Wallace and Guevara’s clash reminds us: even scripted fights leave real scars. Will the laughter last? Fans, holding breath for the sequel that isn’t, bet on tension’s enduring spark.
