She's a little bit country, she's a little bit rock 'n' roll – and Reba McEntire and Kelly Clarkson have hit the road to give fans a little bit of both. "You're feisty, you're fun, you let me sing harmonies... I'm a happy camper," the country legend gushes to the former Idol champ in this new video from behind the scenes of their "2 Worlds 2 Voices" tour, which just kicked off. (See the rest of it here.)

The pair first hooked up for the CMT show Crossroads, and it worked so well, they decided to take their act on tour. Meanwhile, McEntire's former Reba costar, Melissa Peterman, is blogging from the road: "Reba and Kelly are having a ball and I think we are bonding more and more. I like to call us the Three Musketeers. So far I am the only one calling us that but I am sure it is going to catch on."
