Beyoncé Knowles' mother Tina is hounding her daughter for more children.

The superstar singer and her music mogul beau Jay-Z welcomed daughter Blue Ivy into the family in January.

Tina is also grandmother to her daughter Solange's son Daniel.

Although Tina's offspring has produced two children thus far, the matriarch wants more.

Although speculation is rife that Beyoncé is expecting her second child, Tina is sad to report that this simply isn't true.

"It''s gonna happen when it''s time, but not right now," Tina told Access Hollywood.

'Of course I want more grandchildren! I harass Beyoncé all the time."

Beyoncé has spoken previously about her love of being a mother.

The songstress is fond of everything about parenthood, even changing diapers.

'Actually, Jay-Z is very good. We both change diapers. I love changing diapers,' she told Anderson Cooper during an interview on Anderson Live recently.

'I love it. I love every moment of it, it's so beautiful. I love it all.'
