Tina Knowles has spoken.

Her superstar singer/actress daughter Beyonce, 31, isn't pregnant.

In a statement to Access Hollywood, Mama Knowles addressed the rumors that Beyonce was pregnant after she was spotted at La Marina restaurant yesterday in the Washington Heights section of New York City with her husband Jay-Z, music producer Swizz Beatz and Memphis Bleek.

But, Tina's statement dispelled those 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 was also photographed sipping alcohol while at the restaurant, but vh1 reported that witnesses said she never actually sipped from the glass.

This is the photo that launched an Internet craze yesterday. It's of Beyonce wearing a tight leopard print dress with a small bulge in her belly area. To make matters even more cryptic, when the media asked Beyonce's rep if the rumors were true, she responded by saying she does not comment on Beyonce's personal life.

Beyonce has stated that she eventually does want to have more children, but she doesn't know when or how many.

"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 told Star U.K.

The star's Billboard record-breaking daughter Blue Ivy Carter was born eight months ago in New York City.
