The "Since U Been Gone" singer was spotted by fans as she headed to the stage, and in one clip recorded by fan Zoe Minton, she stumbles a bit.
While crossing a red carpet at Indianapolis Motor Speedway, Clarkson tripped, much to fans' surprise. However, Clarkson caught herself, avoiding a major catastrophe.
After catching her self, the Voice coach raised both her hands up in the air triumphantly and curtsying, much to fans' delights.
Clarkson herself acknowledged the snafu on her own Twitter account, laughing off the moment and blaming an imaginary crack for the slip-up.
Clarkson fans reacted to the viral moment with glee.
They loved the way the original American Idol winner handled the situation with grace, and they were relieved she was not injured in the incident.

#Indianapolis500 Thank you @kellyclarkson for your beautiful voice singing our National Anthem. You didn't try to " put your own spin on it" and "make it your own" like so many others. You stood and proudly sang it as it should be. God bless.— knicksfan36 (@cynthiacarnival) May 26, 2019
Clarkson can regularly seen on NBC's The Voice as one of the four coaches mentoring talent.
