Beyoncé pregnant: her mother Tina Knowles knows the sex of her baby

“Yeah they know what they’re having,” Tina, 57, told Life & Style at the Angel Ball in New York City on Monday. “But I’m not telling!”

Fortunately for Beyoncé, whose schedule is always hectic, she’s already been through the morning sickness period and now she’s having her first pregnancy craves.

“She went through it, but she’s got past it now,” Tina said. “She’s doing really good. She’s busy.”

“She’s craving waffles. The normal – just wanting to eat!”

For Tina, it’s not the first time she takes on the role of a grandmother. Beyoncé’s sister Solange was the first to offer her grandson Julez, now 7.

Yet, she’s still excited about welcoming a new addition to their family.

“She’s going to be an awesome mom,” she gushed. “I think it will slow her down somewhat, but I think she’ll be the same great person she’s been.”

Not forgetting to mention her son-in-law, Tina concluded: “I think he’s going to be awesome,” she said. “They are very, very happy and just glowing. It’s great to see.”

Beyoncé is expected to give birth in February.
