The wife of jailed Mexican drug lord Joaquin "El Chapo" Guzman has pleaded guilty to helping her husband smuggle narcotics into the US.
Emma Coronel Aispuro, a 31-year-old former beauty queen, could face up to life in prison.
Coronel admitted three counts, including drug trafficking and money laundering, during a court appearance in Washington.
She answered "guilty" three times when asked by the judge what her plea was. Coronel will be sentenced on 15 September.
US authorities arrested her in February at Dulles International Airport outside of Washington on suspicion of aiding her husband's drug smuggling business.
Coronel was accused of conspiracy to traffic vast amounts of cocaine, methamphetamine, heroin and marijuana for importation into the US.
Guzman was the leader of the Sinaloa Cartel, one of Mexico's most notorious drug trafficking groups.
He ran an operation that delivered hundreds of tons of narcotics into the US and was behind multiple murders of those who crossed him, according to court filings.
He was extradited to the US in 2017 to stand trial, and was convicted and sentenced to life in prison two years later.
Coronel, according to the Justice Department, took part in cartel activities and allegedly assisted in two plots to help Guzman escape from a Mexican prison, including the successful first one in 2015.
A dual US-Mexico citizen and the mother of twins by Guzman, Coronel, 32 years younger than her husband, appeared in court nearly every day of his three-month trial in New York.
She had been barred from all contact with him during more than two years of pretrial detention.
But during the trial, each day as he entered and left the courtroom, Guzman touched his heart and blew her a kiss.
During the trial, there were suggestions that she was involved in his business and prison escape, but authorities let her come and go freely.
Guzman is locked up in the highest-security prison in the US, the ADX federal prison in Florence, Colorado.
