Gabriel Guevara, the 24-year-old Spanish actor whose smoldering portrayal of Nick Leister in the Culpables trilogy has fans buzzing worldwide, is quickly becoming one of Hollywood’s most talked-about rising stars. With his chiseled features, intense gaze, and undeniable charisma, Guevara has turned the role of the brooding bad boy in Prime Video’s Culpa Nuestra (Our Fault) into a cultural phenomenon, drawing comparisons to early heartthrobs like a young Antonio Banderas. As the third installment of the steamy romance series dropped earlier this month, Guevara’s performance—balancing vulnerability with raw edge—has sparked viral memes, fan edits, and endless debates about whether Nick’s redemption arc hits harder than his looks. But behind the on-screen allure lies a grounded actor navigating fame’s fast lane, from Madrid roots to international spotlights.

Born Gabriel Alejandro Guevara Mourreau on February 6, 2001, in Madrid, Spain, Guevara grew up in a creative household that set the stage for his career. His father, Michel Mourreau, is a French-Cuban dancer and performer, while his mother, Marlène Mourreau, is a French actress and model known for her work in European television and theater. This artistic lineage exposed young Gabriel to the entertainment world early on, with family trips to sets and stages fostering his interest in performing. “I’ve always been around cameras and lights,” Guevara told Spanish outlet El País in a 2023 interview. “But I wanted to carve my own path, not ride on names.” He attended local schools in Madrid, balancing academics with acting classes at the prestigious Juan Codina Studio, where he honed his craft alongside peers in Spain’s vibrant youth theater scene.

Guevara’s breakout came unexpectedly in 2023 with Culpa Mía (My Fault), the first film in Mercedes Ron’s bestselling Culpables trilogy adaptation. Cast as Nicholas “Nick” Leister—a wealthy, tattooed racer with a troubled past and a forbidden romance with stepsister Noah (Nicole Wallace)—Guevara auditioned on a whim after modeling gigs for brands like Pull & Bear and Bershka caught casting directors’ eyes. “I read the books and saw Nick as more than the bad boy,” he shared with Cosmopolitan Spain. “He’s layered—anger from loss, but craving connection.” The film, directed by Domingo González, exploded on Prime Video, topping charts in over 190 countries and amassing 50 million views in its first week. Guevara’s chemistry with Wallace—intense stares, heated arguments, and tender moments—fueled the hype, turning the duo into social media darlings.

By 2024’s Culpa Tuya (Your Fault), Guevara had solidified Nick as a complex anti-hero. The sequel dives deeper into Nick’s psyche: Fresh from law school, interning at his father’s firm, he’s torn between corporate polish and street-racing thrills. “Nick’s evolution mirrors my own growth,” Guevara noted in a YouTube interview with Prime Video. “From impulsive teen to a man facing consequences.” The film’s success—another global hit—led to Culpa Nuestra, released October 16, 2025, where Nick’s story peaks amid family betrayals, a lavish Ibiza wedding, and Noah’s ultimatum. Guevara’s physical transformation—bulked-up physique from gym sessions and stunt training—adds grit, but it’s his emotional depth that shines. “That final scene wrecked me,” he confessed to ET Canada, referring to Nick’s vulnerable confession. Critics agree: Variety called his performance “magnetic,” praising how he “elevates the romance beyond steam to substance.”

Off-screen, Guevara’s life echoes Nick’s intensity but swaps drama for discipline. Single since a brief 2022 romance with co-star Nicole Wallace (rumors they dated during Culpa Mía filming were quashed as “on-set chemistry”), he focuses on career and family. “I’m all about balance—work hard, rest harder,” he posted on Instagram (@gabrieloxguevaraa), where his 2.5 million followers lap up gym selfies, travel snaps from Madrid to Milan, and behind-the-scenes teases. A self-proclaimed “adrenaline junkie,” Guevara races motorcycles in his downtime, a hobby that informed Nick’s speed demon side. “It helps me channel that energy,” he told Men’s Health Spain, crediting it for his role prep.

Guevara’s ascent hasn’t been without hurdles. In September 2023, during Culpa Mía‘s Venice Film Festival premiere, old allegations of sexual assault from 2017 resurfaced, stemming from an anonymous complaint in France that led to a brief detention. Guevara denied the claims, calling them “false” and noting no charges were filed. “It’s tough when lies spread,” he said to Spanish media, emphasizing his commitment to respect. The controversy fizzled, but it underscored fame’s double edge—boosting visibility while inviting scrutiny. Prime Video stood by him, with reps stating, “We support our talent amid unproven allegations.”

Beyond Culpables, Guevara’s resume grows. He starred in 2025’s Alas De Ciudad, a Spanish thriller about urban survival, and voices a character in an upcoming animated series for Netflix Spain. Modeling contracts with Dior and Calvin Klein keep his face in magazines, while endorsements from energy drinks to sportswear pad his estimated $2 million net worth. “I want roles that challenge me,” he told GQ Mexico, eyeing Hollywood crossovers like a rumored spot in Fast & Furious 11. Mentors like Antonio Banderas, whom he met at a Madrid event, advise patience: “Build your craft first.”

Guevara’s appeal lies in his everyman charm—fluent in Spanish, English, and French, he connects globally. Fans gush over his 6’0″ frame, dark curls, and piercing eyes, but he credits authenticity: “I’m just a guy from Madrid who loves telling stories.” In Culpa Nuestra, that shines through Nick’s arc—from arrogant heir to devoted partner, mirroring Guevara’s own maturation under the spotlight.

As 2026 approaches, Guevara eyes directing: “I’d love to helm a short film.” With the trilogy wrapped, he’s open to spin-offs: “Nick’s story could continue—who knows?” For now, he’s basking in the glow, thanking fans in heartfelt posts. “You made this possible,” he wrote after Culpa Nuestra‘s premiere.

In an era of streaming sensations, Guevara embodies the new leading man: Talented, resilient, and relentlessly watchable. Whether racing hearts as Nick or charting his own path, this Spanish export is just getting started.
