JAY-Z says it’s no huge mystery why he and his wife Beyoncé decided to name their newborn twins Rumi and Sir (a daughter and son respectively). Rumi was named after 13th Century Persian poet Jalāl ad-Dīn Muhammad Rūmī. ” Sir” was inspired by Hov’s only son’s regal aura.

“Rumi is our favorite poet, so it was for our daughter,” Jay-Z explained during Part 2 of his interview on the Rap Radar podcast. He was sitting down with RR’s Elliot Wilson and Brian ” B Dot” Miller in an interview that was taped in early August at JAY-Z’s California estate. “‘Sir’ was like, man, come out the gate. He carries himself like that. He just came out, like, Sir.”

JAY also revealed that he delayed going on tour in support of his highly lauded 4:44 LP to have a few months of bonding time with the pair of newborns. He said the twins would be coming out on tour with him. You better believe Beyoncé and the couple’s eldest child Blue Ivy will be with him as well. Rumi and Sir were born on The morning of June 13, two days before Jay was inducted into the Songwriter’s Hall of Fame.

Other highlights of the interview include JAY saying he’s done with rap beef and even told stories of him squashing old rivalries with Fat Joe, Jim Jones and Prodigy of Mobb Deep. The Rap Radar Podcast can be found exclusively on JAY-Z’s streaming service Tidal.
