Coon is pregnant with her first child with husband Tracy Letts, her co-star in “The Post.” Last week, Coon debuted her baby bump at the Critics’ Choice Awards, but took a few days before confirming the news on Tuesday. Coon, 36, and Letts, 52, tied the knot in 2013 after working together in the Broadway production of “Who’s Afraid of Virginia Woolf?”
