The big event of the week was the opening of the Metropolitan Opera’s 2017-18 season. As might be expected, a lot of the big stars had a lot to showcase on social media, many of them prepping for the opening of their respective productions.

In addition to her big week at the Met, playing Adalgisa at opening night of “Norma,” mezzo Joyce DiDonato also appeared on “Full Frontal With Samantha Bee.”
