Sean “Diddy” Combs, once the undisputed king of hip-hop, now finds himself grappling with an entirely different kind of rivalry—one that has erupted inside the grim walls of Brooklyn’s Metropolitan Detention Center (MDC). The disgraced music mogul, facing decades in prison on sex trafficking charges, is reportedly fuming over the attention his fellow inmate, Luigi Mangione, has been receiving, reported the New York Post.
The rise of the ‘CEO killer‘
Mangione, a 26-year-old accused of gunning down UnitedHealthcare CEO Brian Thompson in December, has become an unexpected celebrity among inmates. Dubbed the “CEO Killer,” Mangione’s alleged crime—a cold-blooded murder tied to a manifesto railing against health insurance companies—has struck a chord with his fellow prisoners. According to insiders, Mangione has been given a hero’s welcome behind bars, with inmates rallying around his anti-corporate message.
“He’s like a folk hero in here,” a source told The Daily Mail. “A lot of these guys have their own beefs with the healthcare system, and Mangione’s story resonates with them.”
Diddy’s ‘Tantrums’ over lost spotlight
But not everyone is cheering. Combs, who entered MDC in September as its most famous inmate, is reportedly seething. Once the center of attention, the 55-year-old rapper now finds himself overshadowed by Mangione’s notoriety.
“Diddy has been throwing tantrums,” a source revealed. “He can’t stand that Luigi is the one everyone’s talking about. Even in prison, his ego is out of control.”
The situation has escalated to the point where Combs has allegedly placed Mangione on his “s–t list,” despite the two men never having spoken.
A fall from grace
Combs’ rage is a stark contrast to his diminished power within the prison walls. Once a titan of the music industry, he now faces allegations of hosting non-consensual “Freak Off” parties, with federal agents uncovering mountains of incriminating evidence, including hundreds of explicit videos and a stockpile of baby oil. Charged with racketeering, sex trafficking, and transportation to engage in prostitution, Combs could spend the rest of his life behind bars.
Mangione, meanwhile, faces his own grim fate: 11 counts, including first-degree murder in furtherance of terrorism. Authorities claim his manifesto was a chilling prelude to the public assassination of Brian Thompson, a crime that shocked the nation and left the corporate world on edge.
A battle for attention
For now, both men remain confined to the same facility—Combs in general population, Mangione in protective custody. But those close to the situation say the rivalry is far from over.
“Diddy’s entire identity is about being the biggest star in the room,” a former associate remarked. “Now he’s not even the biggest star in prison. It’s eating him alive.”
As the drama unfolds inside MDC, one thing is clear: fame, ego, and grudges don’t disappear in prison—they just take on new, darker forms.
