AceShowbiz - Actor David Tennant and his wife Georgia Moffett are expecting their fifth child.
"What's weird about it is that we're now getting lectures on birth control from our 17-year-old son, and that should definitely be the other way around," Tennant, 48, said. "He says, 'Come on, do I really need to teach you the basics?' "
Tennant's other kids are aged eight, six, and three.
