O’Mara took to social media to announce the news and said, “Surprise!!! I’m am so excited to share that I will be stepping in to sing Donna Anna for the October 20 and 25th performances at the Met Opera!

I am honored to be debuting this role now at the Met, with this magnificent cast! And, I hope to see some of you there.”
