US Weekly is reporting that the 29-year-old pop singer is in her first trimester and quotes an unnamed source as saying the pregnancy was a surprise.

"B was shocked. She loves kids, but she wasn't ready to be a mother just yet," the source told the magazine. "She really wanted to get her album done and tour the world again."

The web site also quoted sister Solange as saying Beyonce would make "a great mom" and record executive Kevin Lies as saying his rapper pal Jay-Z, whose real name is Shawn Carter, "has been all about family."

In interviews after her 2008 wedding to the 40-year-old "Empire State of Mind" rapper, Beyonce, known for her chandelier earrings and skimpy skirts, said she would like to have a family but that she had no timeline.
