The `99 Problems` rapper and his wife Beyonce Knowles are proud parents to 16-month-old Blue Ivy and Jay-Z`s mother, Gloria Carter, revealed her son is besotted with the tot.
She told Us Weekly: "It warms my heart to see how he interacts with his daughter. And when she says, `Papa,` he just melts. He`s a great dad.
"The amazing thing about being a grandmother is that you go get the kids, but when you`re tired, you can take them home!"
When asked if her son and his wife are planning more kids in the future, Mrs Carter responded: ""I think so!"
Beyonce recently admitted she would love to give her 16-month-old daughter a sibling, because she enjoyed such a close relationship with her younger sister Solange Knowles, 26, when they were growing up.
She said: "I would like more children. I think my daughter needs some company. I definitely love being a big sister."
When pressed on when she may have another child, she added: "At some point, when it`s supposed to happen."
