Tina Knowles turned 58 Wednesday. She is a fashion designer known for her work with Beyoncé on the clothing line House of Deréon. She designed many of the costumes for Destiny's Child as well. Tina will soon be a proud grandmother to her second grandbaby. Daughter Solange has a son.

Rumors continue to flare regarding her soon-to-be-delivered grandchild. Beyonce was set to give birth Wednesday, according to a claim by the Web site Media Takeout. As of 4:30 p.m. on Wednesday, the 30-year-old superstar had yet to have the child.

Gossip has been spreading since Christmas that Beyoncé had already given birth. Last week, Twitter users picked up word that Beyoncé had had a baby girl and named her Tiana May Carter. Then reports said she would be giving birth at St. Luke's Roosevelt Hospital in New York City .

On New Year's Eve, the singer was supposed to make an appearance at Dick Clark's Rockin' New Year's Eve 2012 but failed to show. Co-host Ryan Seacrest announced that she could not make it because she's about to give birth.

Obviously, Beyoncé couldn't be here tonight because she's about to give birth to her first child, Seacrest said. A pre-recording of her performing I Was Here in London played instead.
