Sean “Diddy” Combs is “throwing tantrums” about the attention fellow inmate Luigi Mangione has taken from him inside their notorious New York City lockup — and that may put the accused CEO killer on the disgraced rapper’s “s–t list,” a source told The Post Tuesday.
When Combs was arrested on sex trafficking charges on Sept. 16, he was the most famous prisoner at the Metropolitan Detention Center (MDC) in Brooklyn.
But his reign was short-lived.
After Mangione, 26, was arrested for allegedly gunning down UnitedHealthcare CEO Brian Thompson in early December, he was booked into the same facility as the 55-year-old music mogul.
Since he arrived at MDC, Mangione — who is being held in protective custody — has become a sensation among other inmates, the Daily Mail reported.
Mangione is reportedly receiving a hero’s welcome on the inside, with other inmates expressing their own troubles with health insurance.
But that attention has apparently rankled Combs, who is housed in the general population of starstruck inmates.
“Diddy has been throwing tantrums over the fact that Luigi is getting all of the attention in prison and is being revered as a hero after literally murdering someone on camera,” a source told the outlet.
“Even in prison, Diddy’s ego is bigger than life,” they added.
Combs’ reaction comes as no surprise to a former member of his inner circle who was recently financially cut off.
“He always wants to be the center of everything,” the former insider groused to The Post.
“If he feels like anyone takes his attention, he doesn’t take it well. He gets pissed off, and if he has the power to do it, he makes the other person’s life miserable.”
But for the first time in decades, Combs has very little power to do anything about threats to his popularity.
He is facing decades behind bars.
Federal agents raided his Los Angeles and Miami homes in March, seizing hundreds of sex videos and a mountain of sex paraphernalia — including 1,000 bottles of baby oil and lube.
In a statement, the US Attorney’s Office alleged that sex parties he hosted, called “Freak Offs” were not always consensual.
Authorities charged Combs with racketeering conspiracy, sex trafficking and transportation to engage in prostitution.
Mangione, on the other hand, faces life in prison on 11 counts, including first-degree murder in furtherance of terrorism.
Authorities say that he gunned down Thompson days after he wrote a manifesto against insurance companies.
Combs and Mangione share the same legal team, but have never spoken to each other.
Both men will remain at MDC for the foreseeable future — and friends suspect that Combs will perpetuate a one-sided rivalry.
“He’s going to have [Mangione] on his s–t list,” says the Diddy insider.
“He has to be the biggest star wherever he goes. It’s all that matters to him.”
