"They are both absolutely thrilled and can't wait to become a proper family. They don't know what they're having but don't mind either way.
"The rest of the band are just as chuffed and are looking forward to meeting the new arrival as he or she will be the first Kings of Leon baby."
The couple wed in 2009.
