When country singers get together on tour, there are bound to be some silly shenanigans backstage. When these country singers happen to be brothers, you can expect pure insanity. Kicking off this week's best tweets are Lady Antebellum's Charles Kelley and his prankster brother Josh Kelley. The Kelley brothers were on tour together, and on the last night of Josh Kelley's stint on Lady A's tour, the guys got together with their band and crew members in some crazy bathrobes for a photo opp. They look hilarious! Also appearing in this week's Twitter roundup are Scotty McCreery, who channeled his inner dog on a car ride home, Martina McBride and Wynonna Judd, who were celebrating their kids' birthdays, and Alan Jackson, who congratulated his friend George Jones for his lifetime achievement Grammy recognition. See what your favorite country stars were chirping about this past week!
