The Grammy Award-winning artist is said to be in her first trimester of pregnancy, which reportedly came as something of a surprise.
"B was shocked. She loves kids, but she wasn't ready to be a mother just yet," said a source close to the singer. "She really wanted to get her album done and tour the world again."
Another insider said Beyonce, 29, believed "this is a gift from God, and she's so happy."
The couple have not yet confirmed the news.
