The rapper, whose real name is Shawn Carter, was accused in a lawsuit of raping a 13-year-old girl at a party after the 2000 MTV Video Music Awards with Combs.

Jay-Z would “deploy any tactic necessary” to defend himself against allegations that he raped a 13-year-old girl at a party that he attended with Sean “Diddy” Combs—including throw the disgraced music mogul “under the bus,” according to a report.

The rapper, whose real name is Shawn Carter, “has zero loyalty to Diddy” in the wake of a civil lawsuit filed against him about an encounter at a 2000 MTV Video Music Awards, a source told the Daily Mail.

“Jay-Z would absolutely throw Diddy under the bus if that is what it took to clear his name and walk away from this,” the source said to the outlet.

The insider also claimed that Carter, 55, has distanced himself from Diddy since he was arrested on federal charges for sex trafficking and racketeering.

“The moment Diddy was arrested, Jay-Z scrubbed him from his existence,” the source said.

“The only thing that he cares about is him never stepping foot inside a jail cell and his family being safe. Jay-Z is extremely powerful and will deploy any tactic necessary,” the source added.

The insider also claimed that Carter was “appalled” by footage leaked earlier this year that showed Combs attacking his ex-girlfriend Cassie Ventura.

“The video was a deciding factor for Jay when announcing that he and Diddy weren’t close,” the source said.

The bombshell allegations against Carter were revealed earlier this month when his name was added to one of several lawsuits filed over the last year against Combs.

Carter, 55, has called the allegations “idiotic” and vowed not to give the accuser, who has not been identified, “ONE RED PENNY.”

His lawyers have seized on an interview that aired on NBC News with the alleged victim, claiming that her recollection of events reveals “factual inconsistencies” and “timeline impossibilities.”

Carter has also attacked the accuser’s lawyer, Tony Buzbee, who has filed multiple lawsuits for the alleged victims of Combs.

“This lawyer, who I have done a bit of research on, seems to have a pattern of these types of theatrics,” Carter said.

The source told the Daily Mail, “He is going after Buzbee for himself and not for anyone else.”

“Any notion that Jay is trying to help Diddy by going after Tony Buzbee is false. He doesn’t care about Diddy,” the source said.

Combs has denied all allegations against him.

Another source told the Daily Mail that Combs is “very happy that he isn’t fighting everything alone.”

“Diddy does enjoy that Jay is fighting against the same person that is accusing him of doing any wrongdoing,’ the insider told the outlet. ”Because if Jay succeeds, it will help Diddy tenfold.”
