Jay-Z's rape accuser has come forward and admitted there were "some mistakes" in her allegations against the rapper.

The 55-year-old has been left reeling after the woman lodged a case accusing him and Sean 'Diddy' Combs of raping her when she was aged 13 in 2000.

After being known only as Jane Doe in her court filing, the Alabama woman has now given an interview to NBS News, calling the alleged sexual assault a "catastrophic event".

But during the interview, she acknowledged three inconsistencies in her account of what allegedly happened the night she says she was raped during an afterparty following the MTV Video Music Awards.

As a result of her chat, the attorney for Jay-Z - born Shawn Corey Carter - has now requested to expedite the case's dismissed in a legal document.

Lawyer Alex Spiro has asked the judge on the case to shorten the filing deadline for the case dismissal from 21 days to one.

The request, filed at a New York court, said it was made in light of the "stunning public disclosures and severe ongoing harm to Mr Carter's reputation".

According to NBC News, the woman in the case claimed her father picked her up after the alleged rape - but her dad reportedly confirmed he has no recollection of doing so.

The alleged victim added she still stood by her memory and claimed ger father has a hard time recalling events from that time period.

She told NBC News: "There are a lot of things, and this is stuff that we argue about constantly, something he said or did back in New York around that time period he just doesn't remember.

"It actually causes a lot of fights sometimes in the household."

The woman also claimed she spoke to musician Benji Madden, 45, at the afterparty where she claims to have been raped.

But a representative for the rocker said he and his brother, Joel Madden, were on tour halfway across the US at the time of the alleged incident.

Images from the night in question show Jay-Z and Combs, also 55, at a location that does not match the alleged victim's description.

She said: "Honestly, what is the clearest is what happened to me and (the) route that I took to what happened to me. Not all of the faces there are as clear.

"So I have made some mistakes. I may have made a mistake in identifying."
