The Kicker Country Stampede, which takes place in Manhattan, Kan., June 26-29, has added Jana Kramer to its all-star lineup.

The 'Love' singer joins previously announced performers Luke Bryan, Eric Church, Chris Young, Easton Corbin, Lee Brice, Joe Nichols, Randy HouserThomas Rhett and more. A full festival lineup is available here.

Camping and reserved seating has already sold out for the festival, including over 200 additional camping sites added by organizers. A limited number of VIP tickets remain available.

"We want to thank the fans for their continued support throughout the years,” says Wayne Rouse, the festival's general manager. “For the first time, the demand for camping has exceeded the supply! However, we want as many fans to have the opportunity to experience Stampede as possible, so we are looking into ways to accommodate even more folks in future years.”
