Congrats to Rascal Flatts' Jay DeMarcus - now he has a son! "People" says Jay and his wife Allison are celebrating the birth of their second child, Dylan Jay DeMarcus, who was born in Nashville on Friday. The couple's latest bundle of joy arrived a little earlier than expected -- he wasn't due until August 1st -- and when Allison went into labor Jay was in Michigan with the group. But that didn't keep him from being on hand for the delivery.

Dylan arrived at 4:02 p.m., and DeMarcus was able to get to Nashville in time for the birth -- and then get back to Detroit in time for the concert. But he had no time to change for the show, and took the stage wearing hospital scrubs! Jay also says he's eager to get back home to his family -- which also includes 19-month-old daughter Madeline -- as soon as possible.
