The 20-year-old beauty - who is one of the final three contestants on the US reality talent show - stumbled as she sang a rendition of Led Zepplin's 'What Is and What Should Never Be'.
However, she didn't let the accident ruin her performance, picking herself up off the floor and carrying on as though nothing had happened.
She was joined on stage during the number by her father playing the electric guitar and later received positive feedback from the judging panel.
Randy Jackson said: "This was one of your best performances ever! This girl is in it to win it!"
The Chicago blonde is up against Scotty McCreery and Lauren Alaina, who both also received high praise.
