Looks like those undercover romance rumors were true after all. More than three months after Keri Russell was linked to her "Americans" leading man Matthew Rhys, People mag has declared them a couple.

The Cold War-era co-stars were snapped last week at New York's Public Theater, where they took in a performance of the Steve Soderbergh-directed play "The Library." According to the mag, they were whispering to each other, and Keri was spied "stroking" Matthew's hair (hair-stroking apparently moves this outing into "date" territory).

Last month, Rhys, 39, brushed off whispers of a romance, which were sparked by repeated sightings of the pair together off-camera, not to mention a steamy spread in GQ.

"That is the best one I love," he told People of the rumors. "I've told [my mom] a million times that there are a million inaccuracies that she's read, [but she still] calls and goes, 'Is this true?' I tell her, 'No! When are you going to get it?'"

Perhaps the actor owes his mom a call.

Russell, 38, reportedly split with contractor husband Shane Deary last summer after seven years of marriage, although she didn't confirm the bust-up until December. They have two children, 6-year-old son River and 2-year-old daughter Willa.
