If you were already excited about Brad Paisley headlining Country Jam 2016, you'll be overjoyed to know that three country more superstars -- the Zac Brown Band, Blake Shelton and Lee Brice -- will be joining him at the Colorado-based festival.

That's right: The four-day festival, which will take place at Jam Ranch, just outside of Grand Junction, Colo., on June 16-19, has revealed its four headliners. Country Jam 2016 will be the 25th year of the festival, and we're not sure if fans' jaws will drop more because of the stunning mountain scenery or because of the talented roster!

Several ticket and camping options -- general admission, VIP passes, premier camping and Country Club memberships among them -- are available and on sale now. Four-day GA tickets have increased to $125 -- the lowest price they'll be from here on out -- so be sure to make your plans early. More information on tickets, camping and the festival as a whole is available at CountryJam.com.

Country Jam 2015's headliners were Toby Keith, Tim McGraw, Keith Urban and the Band Perry, and the lineup also included more than two dozen other acts, such as Kacey MusgravesBilly CurringtonColt Ford, Frankie Ballard, Thompson Square, Parmalee, Logan Mize and LoCash, all of whom made it a festival to remember. With ZBB, Shelton, Brice and Paisley bringing their biggest hits to the main stage in 2016, this year's Country Jam will also be a summer festival that country fans won't want to miss.

Additional acts for Country Jam 2016 will be announced in the coming months. Keep up with the latest from the festival on Facebook and Twitter.
