A New Jersey woman admitted Thursday to slaying her identical twin in a drunken brawl, according to a report.

Amanda Ramirez, 27, stabbed her twin, Anna, at an apartment in the 1200 block of East State Street in Camden just after 5:30 a.m. June 22, according to the prosecutor’s office.

Anna was rushed to nearby Cooper University Hospital, where she died, officials said.

Amanda said she was unsure what spurred the fight between the two during a heavy night of drinking — but knew it ended with her fatally stabbing her twin, according to NJ.com.

Ramirez struck a plea deal with the Camden County Prosecutor’s Office, which downgraded her aggravated manslaughter charge to second-degree manslaughter, the report says.

The judge could give Ramirez as little as three years in prison over the fatal encounter, the report says.
