Blue Ivy is a 'proud' big sister to her new siblings

Nana Tina is the first of the family to speak out since Beyoncé and Jay-Z officially debuted Rumi and Sir Carter on Instagram.

She spoke briefly with Entertainment Tonight saying “We’re very excited!”

She also revealed how big sister Blue Ivy is handling not being the centre of attention anymore in the Carter household. “She’s very proud and very excited,” Tina shared. “She’s a good big sister, she really is.”

“She cares for them a lot,” Tina’s husband, Richard Lawson, added.

Tina also touched on son-in-law JAY-Z’s revealing new album, 4:44, saying she wasn’t surprised at how candid the rapper was on the record because “it’s art”, though she wouldn’t say whether Beyonce was working on another album after giving birth to the twins.
