Beyonce Not Pregnant, Mother Tina Knowles Confirms

Tina Knowles recently denied that her eldest daughter Beyonce is expecting her second child following reports that the singer is sporting a baby bump.

The fashion designer and doting grandmother spoke out after a recent photograph of Beyonce, 31, dressed in a fitted Roberto Cavalli dress went viral on social networking sites. Some fans speculated whether the Grammy award-winning singer was sporting another baby bump but Tina dismissed the rumors.

"It's gonna happen when it's time, but not right now," Tina told Access Hollywood. "Of course I [want more grandchildren] though! I harass [Beyoncé] all the time."

Beyonce and her husband of four years Shawn "Jay-Z" Carter were spotted casually strolling through Upper Manhattan on Sunday, where they dined at LaMarina restaurant in the evening although their 8-month-old baby Blue Ivy was not present.

"I definitely want to have more [children]! I don't know how many. God knows I don't know yet," Beyonce previously told E! News.

The "Single Ladies" singer once spoke about the joys of motherhood and how giving birth to Blue Ivy has changed her life.

"Nothing can describe the feeling. You have the instant connection once you know your child is growing inside you, but when you hold it for the first time, the words can't be found," Beyonce gushed to Star U.K.

"It's an old cliché that the thing expectant moms look forward to the most is holding their child in their arms for the first time, but it's one of those clichés that is a real truth," she added.

The Hollywood power couple has been busy in recent weeks trying to help raise money for President Barack Obama's re-election campaign and in recent days they hosted a $40,000 per head fundraiser in his honor.

They ultimately raised a total of $4 million and President Obama was sure to thank them for all of their efforts.

"To J and B, thank you so much for your friendship. Michelle, Sasha and Malia are mad at me because they aren't here," President Obama told the crowd.

"Beyoncé couldn't be a better role model for our daughters because she carries herself with such class and poise and has so much talent," he went on.
