There’s nothing covert about it: Piper Perabo is engaged to her director-producer beau Stephen Kay, PEOPLE has exclusively learned.
“They’re very happy,” a source who knows the couple says of the Covert Affairs star and Kay, who is a director on the hit USA Network series.
New Zealand-born Kay, who previously worked as an actor on shows like General Hospital, is also a co-executive producer of the show. The final six episodes of season four will resume Oct. 17 after a four-week hiatus.
The Golden Globe-nominated actress, 36, plays a CIA agent on Covert Affairs.
