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 isnýt 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."
