"Despite the happy news, no one was more surprised than the singer herself. “B was shocked. She loves kids, but she wasn’t ready to be a mother just yet,” says a source of the singer, who married rapper Jay-Z in 2008. “She really wanted to get her album done and tour the world again.”

Still another insider says that the singer, who is in her first trimester, realizes that “this is a gift from God and she’s so happy.” Friends of the couple are already expressing their well-wishes for the parents-to-be. “Jay has been all about family since I met him, and he’s always going to be,” record executive Kevin Liles, who has known the rapper for years, tells Us. “I wish them the best.”
