It was recently rumoured the couple ' who married in April 2008 ' were expecting their first child together and although Tina Knowles insists this isn't true, she knows they will be a fantastic mum and dad one day because they spend so much time with Beyonce sister's six-year-old son, Daniel.

She said: "They're good people and they're really positive and they're talented and they've had a lot of practice with my grandson ' their nephew. So I know they're going to make great parents."

"Beyonce is very caring and patient and loving, so I know she'll be a great mum."

Tina says she will be thrilled when the superstar couple do have a child because she loves being a grandmother so much.

She told People magazine: "Of course I am ready for her to have a baby. What grandmother isn't? I can't wait."

While Tina thinks Beyonce will be a great parent she admits her daughter isn't so good at cooking.

She said: "Cooking is the one thing she hasn't gotten into. She hasn't mastered it, but I'm sure she'll be a good cook once she makes up her mind."
