Baby news abounds on the Dixie Chick's official website, dixiechicks.com. Lead singer Natalie Maines posted an announcement that she and her husband, actor Adrian Pasdar, are expecting their second child. No word on the due date, but mom, dad and 3-year-old big brother Slade are said to be excited. Natalie's not the only Chick on baby watch - Martie Maguire and her Irish husband, Gareth, are expecting twins girls later this year. They've decided to name one of the girls Kathleen, after Gareth's younger sister who died in a car accident seven years ago.
