Carrie Underwood Falls Off Stage on Tail End of South Carolina Concert

Check it out … it’s a bit of a subtle moment, but if you look closely, you’ll see Carrie take a bit of a tumble — or at the very least, an awkward stumble — as she starts to descend some stairs toward the back end of the stage.

In a flash, it almost looks like Carrie drops through a hole back there … either way, her disappearance off the stage doesn’t look all that natural — and something clearly went wrong.

You can even hear people in the crowd scream out that she fell … so folks certainly noticed.

Now, it appears Carrie addressed the fall — she posted some photos from her gig this weekend … and touched on something going awry at the end … although it’s a little cryptic.

She writes, “Well, last night sure was fun! And though the ending was quite unexpected, it made for a night we’ll never forget!” CU attached some emojis touching on rain and weather — but it’s possible she might be quietly referring to the fall at the end.
