Rascal Flatts may still in the middle of their winter Thaw Out tour, but the guys have begun working on their 2012 summer plans. The trio, comprised of Gary LeVox, Jay DeMarcus and Joe Don Rooney, haven't hammered out all the details, however, they do know who will be joining them on the road.

"It's going to be all bands," Joe Don tells Country Weekly. "With Little Big Town, Eli Young Band and Edens Edge. It's going to be cool."

The threesome, who spent last summer crossing the country on their inaugural Flatts Fest, admit they are still undecided if they will use the same moniker for this year's trek. "We're just now talking about what we're going to call it," he adds. "But it's always a party outdoors."

Much has changed since the band first hit the airwaves 12 years ago, including their family size. Gary is the proud pop to two girls, while Jay has one daughter (with another child on the way), and Joe Don has a little boy and girl, who he hopes to spend time with while on tour.

"I'm going to try to take them out this summer," Joe Don notes. "Jagger's almost four now and Raquel is 16 months. It's a beautiful thing."

The 'Banjo' singers recently revealed plans to start a new fragrance and clothing lines, in addition to opening a steakhouse in Ohio. The ACM Award nominees for Top Vocal Group of the Year are also working on a film that documents their personal lives and rise to stardom.

Their next album, 'Change,' will hit shelves on April 3. Take a peek at concert schedule here.
