TIMBALAND is mixing business and pleasure. Timbaland is expecting a new baby! According to a credible source, the talented producer is having a baby girl with a woman who works at his record label, Mosley Music Group. The duo aren’t a couple, although Timbaland promises to be “involved in the child’s upbringing.” Our source added: “He’s very excited about the baby and has been very supportive to the mother.” The baby is due at the end of November. Timbaland’s rep did not return repeated calls for comment.
