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."
