BROOKLYN’S Lynn Nottage, who penned a column in The Post this month describing a trip to Africa that led her to write “Ruined,” yesterday won the Pulitzer Prize for drama for the play.

“I was literally sitting in my bathrobe, procrastinating, when I heard the news,” says the 44-year-old playwright, now writing a screenplay about the fall of Rome. “I don’t think I’ll get any more work done today!”

“Ruined,” inspired by her interviews with women in the Democratic Republic of Congo, is set in a brothel at the edge of a rainforest, and describes what Nottage calls “a war that continues to be fought on the bodies of women.”

The play has been extended several times since its Feb. 10 opening at the Manhattan Theater Club at City Center, where it’s scheduled to run until May 10.
