It’s been two months since Beyoncé and JAY-Z‘s family grew from a family of three to a family of five with the arrival of their twins — a daughter named Rumi and a son named Sir. Now, JAY is finally opening up about the meaning behind their baby’s names — which are just as unique as the name they chose for their first daughter, five-year-old Blue Ivy.

“Rumi is our favorite poet, so it was for our daughter,” the 47-year-old revealed during the second part of his interview on the Rap Radar podcast. “And then Sir was, like, man, come out the gate. He carries himself like that. He just came out, like, Sir.”

Fans waited one month to get a glimpse of JAY and Bey’s twins, and of course, the “Hold Up” singer did not disappoint. To celebrate their one-month birthday, she shared an ethereal photo of the twins and announced their names in the caption. Watch the video below to see the stunning trio.

The singer welcomed her twins prematurely on June 14, and they were released from the hospital two weeks later after being treated for jaundice. A source told E! News that Beyoncé “looked amazing and was glowing” while heading home with her new additions.

The 35-year-old welcomed a boy and a girl, though a source told In Touch that the family’s special day was plagued with “a lot of drama” — mostly because of Bey’s father, Mathew Knowles.

The Carters “didn’t want him there because they don’t trust him not to leak private information about the twins — or even worse, take photos,” the source said. And their fears were realized when he ended up confirming their delivery on social media, much to the dismay of fans.
