JANA KRAMER is opening on Blake Shelton's summer tour . . . along with EASTON CORBIN . . . and she's a believer that his drunk tweets mean she better get ready to drink!
She told CMT.com, quote, "Honestly, I'm going to have to prepare my liver for that tour. But it's going to be really fun. He's a great guy. He's really fun to be around as well. It's just going to be a good time."
I can tell ya, Jana, he is definately professional!
