Beyonce's mother has denied reports that her daughter, who is married to Jay-Z, is pregnant.

On Wednesday (October 20), Us magazine said that the singer had been left surprised by news that she was pregnant.

However, her mother, Tina Knowles, has denied the reports, which are the latest in a string of reported pregnancies for the star.

“The truth is it's not Beyoncé that's pregnant,” she said during a taped appearance on The Ellen Degeneres Show.

Kinwoles joked that it was her who was pregnant, before adding: “With all the rumors, by now I should have about five or six grandchildren."

Jay-Z and Beyonce married in 2008 but have rarely discussed their relationship with the media.
