"It's just a progression," explained Underwood in The Hollywood Reporter last week, "A different sound without losing myself in it. I'm not taking some crazy musical departure from what I've done, but it definitely feels different. It will feel different, look different, and sound different."

As for singing with Miranda Lambert, with whom she collaborated on Lambert's new single Somethin' Bad, Underwood assured fans that they would team up again soon, just not on her next album.

Fans can turn to Country Weekly if they are in need of a little dose of Underwood and Lambert together in action. The chart-topping pair are featured on the July 14th cover of Country Weekly.

Underwood has also been busy setting up to tour the country this summer, including a performance for NBC and a visit to The Grand Ole Opry.

On Twitter this afternoon she announced that she will be joining the Global Citizen Festival this fall. The event will take place on the Great Lawn in Central Park on Saturday, September 27, 2014. The event is free, but ticketed, and will included performances by Jay Z, Fun., Tiesto, and The Roots.

The singer just finished up a relaxing July 4th weekend picking blackberries in Provo, Utah, where she also performed at the Freedom Festival. Underwood is set to resume her tour this month.
