Tina Knowles can't wait to say hello to grandchild number two!

"I'm the most excited I can be. This is my second time around," Knowles, 57, told Us Weekly at Monday's Angel Ball in NYC. Her eldest daughter Beyonce, of course, is now expecting her first child (with husband Jay-Z); Beyonce's baby will have an older cousin in 7-year-old Julez, the son of singer Solange Knowles, Tina's younger daughter.

"She's going to be an awesome mom," House of Dereon designer Tina gushed of Beyonce, 30.

One thing the family won't be revealing until the February birthdate? The baby's gender. "Yeah, [I know the baby's gender]. But I'm not telling!"

Meanwhile, the pregnancy is going along quite smoothly. "She had morning sickness," Knowles revealed. "But she's over it and she's doing really good...she's very busy."

The "Love on Top" diva's number-one craving, according to her mom? "Waffles!"

Once the baby arrives, motherhood "will slow her down somewhat," Tina predicted. "But I think she'll be the same great person she's been."

Dad-to-be Jay-Z (real name: Shawn Carter) is also set to rock out as a parent.

"Jay-Z is going to be an awesome," Tina said of her son-in-law. "They are very, very happy and just glowing, and it's great to see."
