Brooks, who is the biggest-selling country star in music history, is doing nothing to dampen fans' hopes of a comeback tour. On the star's website, a cryptic message reads "The wait is over…7/7," as lightning and thunder crash in the background.

Music fans and magazines, such as Rolling Stone, have been asking when Brooks, who is married to country star Trisha Yearwood, will embark on a comeback tour.

"We're going on a world tour in 2014," Brooks told ABC's Good Morning America last year. "It sure feels good to get to throw your hat back in the ring…. All my babies are fine with it. Ms. Yearwood is fine with it. So now I get to do what I love to do, which is play music. I get to be with the person I want to be with, which is Ms. Yearwood."
