UPDATE: Tina Knowles tells Ellen DeGeneres the rumor isn't true.

Could Beyonce Knowles be on way to having her own "Baby Boy"?

According to several reports, the 29-year-old singer is expecting her first child with rapper Jay-Z. The two have been married sine April 2008.

"B was shocked. She loves kids, but she wasn't ready to be a mother just yet," an insider told Us Weekly. "She really wanted to get her album done and tour the world again." Despite the surprise, another source claims the performer recognizes that "this is a gift from God and she's so happy."

Earlier this month, Beyonce -- who is supposedly in her first trimester -- made an appearance with Tina Knowles (her fashion designer mother) on the Today show. Check out the clip above and see if you notice anything different about her. Is that "glow" really about her mom?
