UPDATE: Beyonce's mom Tina went on 'Ellen' and shot down the pregnancy rumors.
"I'm here to clear the rumors up. The truth is that's it's not Beyonce that's pregnant. It's me," she joked, in an interview to air Thursday. "I'm kidding y'all. I'm 56. No, no, it's not true. Not right now."
"B was shocked. She loves kids, but she wasn't ready to be a mother just yet," a source told the magazine. "She really wanted to get her album done and tour the world again."
Another source said Beyonce is in her first trimester and feels "this is a gift from God and she's so happy."
Beyonce appeared on 'Today' two weeks ago in a form-fitting dress.
