Carrie Underwood Takes a Tumble During Texas Concert

By Laura Ferreiro

It's a performer's worst nightmare – you're flaunting your stuff on stage in front of thousands of adoring fans and then suddenly…you fall flat on your face. Carrie Underwood suffered such a fate when she took a plunge during her concert in Corpus Christi, Texas on Thursday night.

The singer was wearing massive stilettos and a long top that hung very low in the back – a recipe for disaster. She was rocking out and strutting her stuff on stage when a misstep caused her heel to get caught and she took a tumble backwards.

A consummate pro, the former "American Idol" continued singing as though nothing had happened, even though she had injured herself.

Not surprisingly, the good-natured star had a sense of humor about the whole thing, tweeting after the show, "Hey, remember that time in Corpus Christi when that girl busted her butt on stage?! Hilarious! Oh wait, that was me! #5inchheels #klutz."

She later tweeted a photo of her left leg in a cast and quipped, "Good news, it's not broken...AND I got some new footwear!"

Here's hoping it heals up quickly and that things go more smoothly for Underwood this weekend when she makes her NFL debut, singing the theme song for NBC's "Sunday Night Football."
