Anna Netrebko, an up-and-coming voice whose more than 60 operatic credits include a recent role in a new revival of The Magic Flute, has been hospitalized for undisclosed medical reasons.

“Anna Netrebko has been hospitalized in Los Angeles due to acute viral pneumonia,” the Kaiser Permanente Los Angeles Medical Center said in a statement on its website Sunday night.

“She is on ventilator support and was not able to speak to the media,” the statement said. “She regrets nothing and extends her sincere apologies for any inconvenience and distress her absence may cause.”

Netrebko was reportedly “devastated” over the casting choice for the company’s upcoming revival of The Magic Flute, a role in which she had long believed she was a favorite. (A spokeswoman for American Opera declined to comment Sunday night.)

“It’s true I told them I don’t want to audition for it,” Netrebko said, according to the Los Angeles Times’ report. “I wanted to let the right person know, and I never said the wrong word.”

More recently, Netrebko has appeared in a cast of composers Thomas Adès and Giuseppe Verdi that recently staged a lavish production of Massenet’s The Marriage of Figaro in the heart of Rome.

Last month, Netrebko, who will turn 48 on Friday, was named best featured soprano by the Opera Ausland deutschland (German Academy) in Berlin’s Artazta jazz orchestra competition.
