Lady Antebellum have been busy on their headlining tour with Josh Kelley and Edens Edge, but not too busy to pay tribute to the troops. The trio dedicated their song 'Hello World' to military veterans past, present and future via Twitter, and even included a photo of themselves on stage.

Also in this week's best tweets, Blake Shelton was thinking about -- who else -- himself. The 'Honey Bee' hitmaker seems to be milking his three Grammy nominations for all that they're worth, not that we can blame him. Lauren Alaina got a new phone number this week, but called her old number to find a voice-alike on the other end, while Frankie Ballard experienced the performance of his life at Madison Square Garden.

Just in time for Christmas, Scotty McCreery announced via Twitter that he unleashed all-new merchandise, which is available on his website, but order now to get the goodies under your tree in time. See what else your favorite country stars were tweeting about this week! meanwhile, blake shelton was thinking about who else but himself.
