It's a bad day for Kelly Clarkson fans!

Kelly announced through Twitter that she has to cancel at least six tour dates due to doctor's orders.

She gave her fans little or no notice as one concert is scheduled to be taking place this evening.

"So bummed that I have to cancel some of my tour dates. This kills me, but doctors are saying I need to rest my voice," the 33-year-old tweeted.

The scheduling affects dates from today and up throughout the next week, ending on September 20.

The cancellations include two stops in Vienna, Virginia, two in Florida – including Tampa and West Palm Beach – one in Raleigh, North Carolina and another in Camden, New Jersey.

That's a lot of disgruntled fans to deal with!

"I can't wait to get healthy and see y'all back on the road soon. I hate canceling," the songstress wrote in a second tweet.
