Sonya Yoncheva has canceled the Dec. 7 performance of “La Boheme.”

The soprano announced via Twitter that she was suffering from Bronchitis for the past two months.

She said, “Dear all, I am extremely sorry to cancel the next show of ‘La Bohème’ due to a bronchitis which pursues me since 2 months. I beg you to STOP speculations and have a little respect because singers can also be sick!!! I am planing to sing the 10 & 12 December. Love to my supporters.”

As a result, Nicole Car, who opened the Royal Opera earlier this year, will sing the role in her place.

She is also slated for “Boheme” and the title role in “Luisa Miller” at the Met. Next year she also embarks on a Verdi tour and will make her role debut as Imogene in “Il Pirata.”

The opera de Paris new production of “La Boheme” also stars Aida Garifullina, Artur Rucinski and Atalla Ayan. Claus Guth directed the new production which is set in space.
