Chiquis, who is on the road in support of her latest album, suffered a miscarriage while getting ready for her concert at the weekend.
Although the singer had not yet shared the news of her pregnancy, she told fans in an Instagram update that a miscarriage was the reason she had to postpone her concert in Albuquerque, New Mexico on Saturday night.
It would have been just the second date of her Diamantes Tour.
"To my fans in Albuquerque," she wrote in an emotional note posted in both English and Spanish. "With a heavy heart, I wanted to let you know that my concert postponement last night happened because of a medical emergency that made it impossible for me to take the stage, physically as well as emotionally.
"While I was at the venue getting ready for the show I suffered a miscarriage."
She added, "I am sorry for the inconvenience this may have caused you. I promise to make the date up to you as soon as possible and your tickets will be honoured. Your understanding means the world to me. My doctor has said I will be able to continue with the tour for my next dates in Texas June 7th, 8th and 9th."
The Latin Grammy-winning artist, who won Best Banda Album for both Playlist (2020) and Abeja Reina (2022), has described her tour as "a celebration of empowerment, self-expression and unity".
Chiquis, full name Janney Marín Rivera, became engaged to her photographer partner Emilio Sanchez a year ago.
She is the eldest daughter of singer Jenni Rivera.
