His casting in the *All-Stars* season was a strategic move by Telemundo to inject international star power and existing reality TV notoriety into the competition. Onestini’s history of intense relationships and controversial moments in European shows foreshadowed the drama he would bring to the Latin American format.

The Explosive Romance with Aleska Génesis: From Novios to Public Battle

The most defining and controversial aspect of Luca Onestini's time in the famous house was his intense relationship with Venezuelan model and fellow contestant, Aleska Génesis. Their connection was immediate and became the centerpiece of the season, providing countless viral moments for fans of the show.

A Whirlwind In-House Relationship

The pair quickly became a designated couple, with their romance blossoming under the constant scrutiny of the reality show cameras. They were officially "novios" (boyfriend and girlfriend) inside the house, giving viewers a passionate, telenovela-like storyline that generated massive ratings. Their dynamic was a source of both fascination and criticism, with many viewers questioning the authenticity of their bond versus its strategic value in the game.

Onestini, the Italian charmer, and Génesis, the Venezuelan beauty, were inseparable, often closing out the live galas with their "Best Love Story" segments. After 119 days of intense confinement, their relationship survived the environment, with Luca emerging as the second finalist, pocketing a substantial $100,000 prize.

Post-Show Scandal and Cheating Allegations

The real scandal, however, erupted shortly after the show concluded. Despite their passionate on-screen connection, the relationship between Luca and Aleska Génesis quickly deteriorated in the outside world. The breakup turned into a bitter and very public feud, which was extensively covered by the press and social media.

The drama reached a fever pitch when Aleska Génesis publicly accused Luca Onestini of cheating on her with "two women." This shocking revelation was made during a live broadcast, turning their once-beloved reality TV romance into a messy public battle. Onestini, in turn, did not shy away from the spotlight, giving "candid details" to the media about their intimate nights together inside the house, further fueling the controversy and the intense media scrutiny surrounding the two reality stars.

This post-show drama provided a steady stream of LSI keywords and search intent, as fans desperately searched for updates on the cheating allegations, the public feud, and the true reason for the split between the former LCDLF All-Stars couple.

Beyond the Romance: Strategic Gameplay and Other Controversies

While his relationship with Aleska Génesis dominated the narrative, Luca Onestini's journey to the runner-up spot was also marked by shrewd strategic gameplay and other notable controversies, cementing his status as a polarizing figure.

The Ex-Girlfriend Drama with Cristina

Even before the season began, Onestini was at the center of a pre-show controversy involving his ex-girlfriend, Cristina. Reports surfaced that Cristina, a fellow reality TV veteran (known from *Big Brother Italy*), had decided to drop out of the *La Casa de los Famosos All-Stars* cast at the last minute. The reason? Allegedly, she was unwilling to participate in the same house as Onestini, suggesting unresolved tension and past drama that added an extra layer of intrigue to Luca's casting.

The Rivalry with the Winner, Carlos "Caramelo" Cruz

Onestini proved to be one of the strongest competitors, lasting the entire 119 days of confinement and becoming the second finalist. His main rival in the final stretch was the eventual winner, Carlos "Caramelo" Cruz, the Dominican influencer. Luca's strategic alliances and ability to survive the elimination rounds—often against popular figures like Rey Grupero—demonstrated his strong fan base and competitive drive. The final vote between the two was incredibly close, highlighting the division among viewers who either loved his charm and strategic play or disliked his controversial demeanor.

The Aleska Génesis Arrest After Eviction

Another shocking moment that indirectly involved Luca was the highly publicized arrest of Aleska Génesis following her eviction from the house. While the arrest was reportedly related to a pre-existing charge of robbery, the timing and the dramatic circumstances of her departure and subsequent legal troubles sent shockwaves through the production and the cast, including a visibly shaken Luca Onestini, who was still inside the house at the time. This incident further amplified the tumultuous nature of the entire *All-Stars* season.

Luca Onestini’s experience on *La Casa de los Famosos All-Stars* was a perfect storm of romance, strategy, and scandal. From winning $100,000 to navigating a public breakup with cheating allegations, the Italian model's controversial run has secured his place as one of the most unforgettable contestants in the history of the Telemundo reality show franchise.
