LOS ANGELES (Reuters) – The mother of pop star Beyonce on Thursday shot down a report her daughter is pregnant, saying that if all the baby bump rumors about the singer were true over the years, she should have five or six grandchildren.

“No, no it’s not true. Not right now,” Tina Knowles said when asked about the report by talk show host Ellen DeGeneres.

One day earlier, Us Weekly magazine published a story saying the “Single Ladies” singer, 29, and her husband, producer and rapper Jay-Z, were expecting their first child.

The Us Weekly story is published in the magazine’s November 1 issue, and on Thursday an Us Weekly spokeswoman told Reuters, “we stand by our reporting.”

But Tina Knowles would beg to differ. She said on “The Ellen DeGeneres Show” that “with all the rumors by now I should have five or six grandchildren.”

In fact, pregnancy rumors have long swirled around the popular singer and her husband, who have been married for more than two years. A spokesman for Beyonce said he never comments on speculation about her private life
