Sarah Silverman and Michael Sheen see ‘Sleep No More’ in New York

The couple made their first red carpet appearance at the Met Gala.

Sarah Silverman and beau Michael Sheen enjoy showing off their new romance — and flying under the radar.

The couple made their first red carpet appearance together in a very public way at this week’s swanky Met Gala, but they were also spotted recently having a more private night out, seeing “Sleep No More” at the McKittrick Hotel.

As the show dictates, the comedienne and the actor wore masks during the performance. According to a witness, they seemed to “enjoy” each other’s company, holding hands throughout the night.
