Now that all three members of Lady Antebellum have gotten hitched, the big question is which one will be the first to pop out a baby!

If Charles Kelley has his way, there will be no baby carriages in band mate Hillary Scott’s near future.

“If Hillary gets pregnant,” he says, “we have to stop touring.”

The trio’s good friend Luke Bryan sparked the question on Monday’s CMA Music Festival: Country’s Night to Rock special on ABC.

While Charles hopes Hillary isn’t first, Hillary, who’s busy being mom to two dogs Hobbs and Baker, is sure Charles will be the first to welcome a Lady bAby.

Other questions Luke posted to the trio? Who’s the messiest on the tour bus? Hillary! And who uses the most hair product? Charles!

Lady Antebellum kicks off the final leg of their “We Owned the Night World Tour” in Australia on September 25^th.
