Anna Netrebko

Soprano Anna Netrebko is extending her pregnancy leave and has withdrawn from performances of Puccini's "La Boheme" at the Metropolitan Opera in New York in December and January.

Netrebko, 36, announced in February that she and her fiance, Uruguayan baritone Erwin Schrott, were expecting, and the Met said Friday she is due to give birth next month.

"She has decided that she will need a few more weeks than originally planned to be ready for her return to the stage," the Met said.

Netrebko's final performance before her maternity leave was a June 27 concert in Vienna, Austria, and she withdrew from a highly anticipated new production of Gounod's "Romeo et Juliette" at Austria's Salzburg Festival.
