Making a rare public appearance out together, Michael Douglas and Catherine Zeta Jones arrived at the opening night of "The Library" in New York City on Tuesday (April 15).

Looking beautiful in black, the 44-year-old actress sported a long, black slinky frock while standing arm-in-arm with her hubby.

The off-Broadway play is officially described as follows, "After Caitlin Gabriel (Chloë Grace Moretz) survives a deadly shooting at her high school, she struggles to tell her story to her parents, the authorities and anyone who will listen. But there are other narratives that gain purchase in the media and paint her in a different light."

This is Catherine and Michael's first red carpet appearance since getting back together after announcing their separation back in August 2013.
