Beyonce Knowles and Jay-Z are expecting their first child, according to a new Us Weekly report.

It seems the pregnancy wasn't planned, according to one of the magazine's sources: "B was shocked. She loves kids, but she wasn't ready to be a mother just yet. She really wanted to get her album done and tour the world again."

Another source says the 29-year-old singer, who is supposedly in her first trimester, believes "this is a gift from God and she's so happy."

Beyonce's publicists have not yet returned our requests for a statement.
