Jennifer Hudson has something new to sing about. The 27-year-old Oscar and Grammy winner gave birth to a healthy baby boy Monday, and named him David Daniel Otunga Jr., after her fiancé. The new child is good news for Hudson, who was struck with tragedy last year when her mother, brother, and nephew were murdered in Chicago. Hudson's career skyrocketed after her success on the 2007 season of American Idol. From there she won big at the Academy Awards for her performance in Dreamgirls, and just this year won a Grammy for a self-titled album.
