Jay-Z revealed why he and Beyoncé chose the unique names Rumi and Sir for their twins, who were born in June. "Rumi is our favorite poet, so it was for our daughter," he said during a podcast interview released on Friday. "And then Sir was, like, man, come out the gate. He carries himself like that. He just came out, like, Sir." Jay-Z also made sure to schedule his upcoming tour for well after the birth of the twins. "I booked the tour for October so I could have at least four months ... to just really bond and see their fingers and s--t like that," he said. Jay-Z also opened up about his daughter, Blue Ivy, ended up rapping a freestyle for one of the bonus tracks on his new album, 4:44. "I can't even listen to that song no more. I only listen to her freestyle, and then I'm like, 'I can't listen to this,'" he quipped.
