In a podcast with Rap Radar, JAY-Z opened up about how he and Beyonce settled on the names Rumi and Sir for their new twins. The first honors a poet and the second honors some baby attitude. “Rumi is our favorite poet, so it was for our daughter,” said JAY-Z, per US Weekly. He's referring to the 13th-century Persian poet Jalal ad-Din Muhammad Rumi, and the uninitiated can dig into the this BBC story explaining why Rumi is perhaps the "most popular poet in the US." As for Sir, well, that's a little more subjective. “Sir was like, man, come out the gate," says JAY-Z. "He carries himself like that. He just came out, like, Sir.” (More Jay-Z stories.)
