It has long been speculated that O.J. Simpson murder trial prosecutors Marcia Clark and Chris Darden had more than a working relationship.

But it’s not just Clark and Darden who are questioned about their potential romance.

“Sarah and I get asked [if] Marcia and Chris had some extracurricular activities,” Sterling K. Brown, who plays Darden in FX’s The People v. O.J. Simpson: American Crime Story, tells PEOPLE of himself and costar Sarah Paulson, who plays Clark.

But all parties involved remain vague about giving a definitive response to the rumors.

“They play very coy,” Brown says of the real-life Clark and Darden. “They smile and they blush and they sort of just don’t confirm one thing one way or the other.”

The attention paid to Clark and Darden’s relationship caught Brown a bit by surprise.

“I didn’t know it was going to take that much attention,” says Brown, who has received rave reviews and Emmy Award buzz for his work on American Crime Story, which airs its finale Tuesday. “But I guess in our story, the only romance that’s there is the relationship between Chris and Marcia.”

But Brown – who also co-stars with Tina Fey in Whiskey Tango Foxtrot and is the lead role in Pulitzer-winning playwrite Suzan-Lori Parks’ Father Comes Home From The Wars (Parts 1, 2 & 3), opening at the Mark Taper Forum in Los Angeles Tuesday – would be entirely open to seeing where the American Crime Story writers would take a fictional Clark and Darden relationship in a spin-off.

“If it means I get to work with Sarah Paulson again, lets ‘ship them and make it happen,” he says.
