Kelly Clarkson returned to her roots - well, sort of - for a rousing rendition of her new single, 'What Doesn't Kill You (Stronger)', on Wednesday night's episode of The X Factor.

Standing before her American Idol judges Simon Cowell and Paula Abdul, Kelly rocked the heck out of the song in a hip-hugging gold dress, marking one of her best live performances in recent months.

The song is the second single off her chart-topping CD, Stronger. Her previous single, Mr. Know It All, reached the top 10 on the Billboard Hot 100 charts.
