Miranda Lambert's Keeper of the Flame Tour will end a bit earlier than anticipated: The singer has been put on vocal rest and been forced to cancel her summer trek's final three tour dates.

According to Lambert’s official website, her shows with Kip Moore and the Brothers Osborne in Corpus Christi, Texas (Sept. 15), Austin, Texas (Sept. 16) and San Antonio, Texas (Sept 17) have all been canceled. The singer herself has yet to address the cancellations, but Live Nation reports that the cause is "mandated vocal rest." Ticketholders should contact their original point of purchase for refunds; online and phone orders will be refunded automatically.

Lambert recently released the music video for her new single “Vice.” The song is fans’ first taste of new music from Lambert and was written “at the exact time of the s–t hitting the fan,” the singer says, referencing her divorce from Blake Shelton in the summer of 2015.

“Sometimes when you’re going through something in your life, you may run to some things you shouldn’t and run from some things you shouldn’t,” she explains. “I think this song is an opportunity to just be honest and own it and say, ‘Yeah, I have some imperfections, and I live a life, and here and there I might get in a pickle.’ It’s not about one thing or another. Everybody has a vice they run to when they need comfort, and I think that’s what this song says.”

The release details of Lambert’s upcoming new album have yet to be announced, and while the country star has revealed very little information about her new record, she is adamant that it will reflect what she’s gone through recently.

“Every record I’ve ever made has been a reflection of where I am right then in my life, however old I am. And I’ve never held back at all,” Lambert notes. “But this time, with what I happened to be going through in my life, being honest was never really a choice. Everybody knew anyway. So I just said, I’m gonna journal it, and — good days and bad days — use it for my art.”

“Vice” is available for download on iTunes.
