Today (Oct. 27), “CBS Mornings” shared the second part of Gayle King’s special feature with JAY-Z, complete with a tour of the critically acclaimed “Book of Hov” exhibit in Brooklyn. In the 11-minute segment, the billionaire mogul was asked about Blue Ivy Carter’s participation during Beyoncé’s groundbreaking “Renaissance World Tour,” which he feels is the best of his wife’s career thus far.

“What makes me super proud and, you know, I still get goosebumps from seeing her walk on stage is ’cause Blue’s been born into this world, she’s been born into this life she didn’t ask for. Since she was born, she’s been in scrutiny, and [the] public eye, and everyone has an opinion. Even [as] a little girl, how she keeps her hair,” JAY-Z explained about his oldest daughter. “So for her, to be on that stage and reclaim her power, and the song [that she performed] is called ‘My Power,’ you can’t write a better script.”

He continued, “She came out; it’s 80,000 people. She’s 11, so she’s nervous. I know her. So I know how nervous she was. I know how frightened she was. And she wanted to do it. She wanted to do it the first night, and we were like, ‘Okay, if it’s something you want to do, you can’t just go out there. You gotta go work with the dancers and go work.’ And she worked every day.”

King also inquired about Blue Ivy‘s name and where it came from. “It was supposed to be Brooklyn, that was the name we had in theory. When we got the sonograms, [she] was super small and we were calling her Blueberry,” Hov revealed. “It was like a nickname. For nine months, we were like, ‘Look at the little blueberry!’ It was natural. We just took the ‘berry’ off and just called her Blue.”
