Sixteen-month-old Madeline Leigh is Rascal Flatts' bassist Jay DeMarcus's only child... for now. He and his wife Allison are expecting their second in the summer of 2012. The new baby will be a boy, making four babies 4-years-old or younger on the band's summer tour (see Joe Don Rooney's brood in a few clicks).

DeMarcus often tweets pictures like this one with his little girl, who is obviously his pride and joy. If his son is as handsome as this girl is cute, the couple will be in for some trouble when their offspring get a little older and learn how to look sweet -- on purpose -- to get what they want. DeMarcus is also brothers-in-law to James Otto.
