Beyoncé and Jay-Z's oldest daughter, seven-year-old Blue Ivy, is "queen bee" of their household.
The 'Formation' singer's mother, Tina Knowles-Lawson, has revealed her seven-year-old granddaughter, Blue Ivy, rules the household over her famous parents and twin siblings Rumi and Sir, 19 months.
Tina said: "Blue is the Queen B. The second Queen B."
And the 65-year-old fashion designer went on to explain the twins are already showing signs of very different personalities.
She told the New York Post newspaper's Page Six column: "For the twins, the girl is really going to rule the world, and the boy is kind of laid-back. He just chills like his dad."
