Jay-Z, the star rapper and entrepreneur whose real name is Shawn Carter, was accused in a lawsuit Sunday of allegedly raping a 13-year-old girl with Sean “Diddy” Combs in 2000.

The anonymous accuser, identified only as “Jane Doe,” said the attack occurred after she was driven to an MTV Video Music Awards afterparty.

The federal lawsuit was originally filed in October in the Southern District of New York and listed Combs as a defendant. It was refiled Sunday to include Carter.

Carter’s attorney, Alex Spiro, and his publicist, as well as Combs’ representatives, did not immediately respond to requests for comment. Texas-based attorney Tony Buzbee, who filed the lawsuit, had no comment.

Buzbee has filed multiple lawsuits in recent months – all withholding the names of their plaintiffs – accusing Combs of assault and rape. This is the first lawsuit in which he has named another prominent defendant.

Combs has repeatedly denied all allegations made against him. Federal prosecutors in New York charged him with racketeering, sex trafficking and other crimes in September, and he remains behind bars at the Metropolitan Detention Center in Brooklyn after being denied bail for the third time last month. His trial is scheduled for May 5.

Prosecutors said in a court hearing last month that they were in the process of potentially filing additional charges against Combs in a superseding indictment.

Before the lawsuit was refiled Sunday, “Carter received a letter from plaintiff’s counsel requesting mediation to resolve this matter,” Buzbee wrote in the lawsuit. NBC News has seen this letter. In response to the letter, Buzbee wrote in the lawsuit, Carter filed his own lawsuit against the accuser’s lawyers.

The lawsuit alleges that Doe was raped by Combs and Carter at a house party after the MTV Video Music Awards in New York in 2000, when she was 13 years old.

The lawsuit says a friend dropped her off at the VMAs at Radio City Music Hall. She didn’t have a ticket and approached various limo drivers for access to the show or an after-party.

A driver, the lawsuit says, told her that he worked for Combs and that she “fitted what Diddy was looking for.” He invited her to a party after the show and told her to return to his car later that evening after he transported Carter and Combs, the lawsuit says.

Later, the driver picked them up, the suit says, and after 20 minutes they arrived at a white house with a U-shaped driveway, the suit says. She was required to sign a document that she believed was a nondisclosure agreement upon arrival – and was not given a copy – in order to attend the party, which was full of celebrities and people using marijuana and cocaine, according to the lawsuit.

She was offered a drink that left her feeling “light-headed, dizzy and like she needed to lie down,” the suit says, and went into a room to rest.

Shortly afterward, the lawsuit says, Combs and Carter entered the room, with Combs saying, “You’re ready to party!”

That’s when, she claims, Carter stripped her of her clothes, held her down and raped her while Combs and an unnamed female celebrity looked on. She says Combs also raped her while Carter and the woman watched.

The lawsuit states that she was able to resist being forced to perform oral sex on Combs by hitting him in the neck and that he “stopped.”

After the alleged assault, the lawsuit says, she “grabbed her clothes” and left. She made her way to a gas station where she called her father.

The prosecutor is demanding unspecified damages. The lawsuit is filed under New York’s Victims of Gender-Motivated Violence Protection Act.
