Jay-Z reveals why he and Beyoncé named their twins Rumi and Sir

Jay-Z has revealed he and Beyoncé named their son Sir because of the way the baby "carries himself".

The couple welcomed twins Rumi and Sir Carter earlier this summer. And while their daughter Rumi was named after the couple's favourite poet, the inspiration behind Sir's name is a little more unusual. The rapper told Rap Radar podcast:

“Rumi is our favorite poet, so it was for our daughter. “Sir was like, man, come out the gate. He carries himself like that. He just came out, like, Sir.”

“She got the headphones and she climbed on the little stool, and then she just started rapping. “I was like, ‘Oh, s***.’ I have [her full freestyle] on my phone. Five minutes! Five minutes of her doing that.”

The Empire State of Mind rapper also talked about the hook that went viral when the song was released in early July.

“She kept doing that ‘boom shakalaka, boom shakalaka.’ I was like, ‘Oh, she understands the concept of a hook. “She’s 5, and she understands the concept of a hook. I was like, ‘What the f*** is going on here?’ One of the great memories.”

The 47 year old also revealed that Beyoncé, Blue, Rumi and Sir will be joining him on tour later this year - and that he put off the tour for a few months to focus on family. He explained:

“I booked the tour for October so I could have at least four months to just really bond and see their fingers and s*** like that. “They’ll be with me [on tour] anyway, but I’m just saying, like, [I needed] a space where I’m not doing anything. “I’m just focused on them. I’m not thinking about a show at night or anything like that. That’s why the tour is so far away from the release of the album.”
