Jana Kramer will not only need to warm up her vocal chords for her upcoming tour with Blake Shelton (and fellow opener Easton Corbin) -- she's admitted that she'll also need to prepare her liver, as Shelton's Ten Times Crazier Tour is bound to get a little crazy.

Kramer, who is nominated for two CMT Awards including Female Video of the Year and Breakthrough Video of the Year, is definitely excited about hitting the road with the 'Boys 'Round Here' hitmaker... even if her liver may suffer.

"Honestly ... I'm going to have to prepare my liver for that tour," she tells Wonderwall, acknowledging that Shelton is known for loving a good time. "But it's going to be really fun. He's a great guy. He's really fun to be around as well."

She adds, "It's just going to be a good time, but I'm going to see if I can try to prank him too, out there. That'd be pretty awesome."

Along with a sly bag of tricks, the 'I Hope it Rains' singer will be bringing along a few other essentials. "Must-haves, let's see. My kickboxing gloves because I work out on the road and I love to box. So I have to have that," she says of one of her touring essentials. " My yoga mat, to work out with... I have to have one of my dogs out, either my Puggle out with me, or my boxer. So Brantley and I rotate them -- which ones we have on the road with us."

While Kramer will probably miss her fiance, fellow musician Brantley Gilbert, while she's on the road, Shelton will likely be pining after his sassy second half. Kramer has only good things to say about Miranda Lambert, revealing, "She's a real sweetheart. I don't know her that well, but every time I've met her, she's been really sweet."

Fans will have a great show in store for them on the Ten Times Crazier run, and Kramer will surely have plenty of crazy memories from this summertime tour... if she can remember them.
