Jay was apparently in Detroit when Allison went into labor, but he hopped a flight from the Motor City to Music City and arrived just in time to watch his son be born. Without even ditching his hospital scrubs, People reports, he then hightailed it back to Michigan to perform with Rascal Flatts.
Dylan is the couple's second child, and in December 2010, the pair welcomed daughter Madeline Leigh. Congratulations, Jay and Allison!
