Tina Knowles On Bey’s Pregnancy, “They know what they’re having, but I’m not telling.”

As she should, 57-year-old Tina Knowles, is remaning tight-lipped about the sex of her daughter (Beyonce) and son-in-law’s (Jay-Z) unborn child.

Monday night, while attending Gabrielle’s Angel Foundation for Cancer Research Angel Ball, she told Life & Style,

“Yea they know what they’re having. But I’m not telling..She went through [morning sickness], but she’s got past it now. She’s doing really good. She’s busy. She’s craving waffles. The normal — just wanting to eat… She’s going to be an awesome mom. I think it will slow her down somewhat, but I think she’ll be the same great person she’s been.”
