Lady Antebellum have begun the daunting task of cancelling their summer 2013 tour dates in anticipation of the arrival of Hillary Scott's bundle of joy -- the first baby that will be born into the Lady A clan.

The Grammy Award-winning trio's June 21, 2013 NEBRASKAland DAYS commitment in North Platte, Neb. has officially been canceled, citing Scott's pregnancy as the reason. Lee Brice and rising star Thomas Rhett are still scheduling to perform, but concert promoters will offer fans full refunds if they are not pleased with the to-be-announced act that will assume Lady Antebellum's headliner role.

According to the trio's official website, a few dates in July and August have already been killed, as well. No official word has come for the band concerning their revised touring plans, but it's fair to speculate that their entire summer itinerary will likely be canceled.

“Chris & I are excited to announce that our Christmas gift has arrived a little early this year! We are having a BABY! We feel so blessed!!! – Hillary,” Lady A's leading lady shared last week, announcing her baby-on-the-way.

Scott Married her husband, drummer Chris Tyrrell, on January 7, 2012 in a private winter ceremony. Bandmates Charles Kelley and Dave Haywood are both happily married as well, but Scott is the first to add a baby to the bunch.

The singer gave no indication of a possible due date, but given the timeline of the band's recent cancellations, it looks as though Baby Tyrrell will arrive in early summer 2013!
