In January 2008 she performed the same role at the Royal Opera House, Covent Garden to triumphant acclaim on the opening night, opposite Jonas Kaufmann and Dmitri Hvorostovsky in performances conducted by Maurizio Benini. However, she cancelled three subsequent performances due to suffering a bronchial condition. In May 2008, she made her Paris Opera debut in Bellini's "I Capuleti e i Montecchi" at the Opéra Bastille, with Joyce DiDonato as Romeo. In her first performance after her maternity leave, Netrebko sang Lucia in "Lucia di Lammermoor" when it opened at the Mariinsky Theatre in Saint Petersburg on 14 January 2009, in a production from the Scottish Opera led by John Doyle. She then sang the same role in January and February 2009 at the Metropolitan Opera. Netrebko appeared as Giulietta in "I Capuleti e i Montecchi" at the Royal Opera House in Spring 2009, and as Violetta in "La traviata" in June 2009 at the San Francisco Opera.
