Joaquin “El Chapo” Guzman’s wife on Friday posted Instagram photos of herself laughing outside Brooklyn federal court — a day after she cackled while her drug lord hubby’s mistress wept on the stand.

Emma Coronel Aispuro posted three photos of herself laughing and smiling as she walked out of the courthouse where her husband is on trial, captioned only with a love heart.

The photos were snapped Thursday after the 29-year-old chortled as one of Chapo’s former mistresses, Lucero Guadalupe Sanchez Lopez, took the stand to testify against her former flame — then broke out in sobs.

Before Sanchez’s outburst, Coronel looked less thrilled — sitting stonefaced in the courtroom while Guzman’s sidepiece discussed their affair.
