Piper Perabo and Stephen Kay Tie the Knot

Mission accomplished: Piper Perabo is married!

The Covert Affairs actress wed her director-producer fiancé, Stephen Kay, on Saturday, her rep confirms to PEOPLE.

The couple tied the knot in New York City and the bride and groom continued the celebration with a New Orleans band at their reception, according to reports.

Perabo, 37, and Kay – who has also worked as an actor on shows including General Hospital – work together on the hit CIA series and were engaged in September.

“They’re very happy,” a source told PEOPLE at the time.

The show, now in its fifth season, airs Tuesdays on the USA Network.
