Kelly Clarkson Performs on Dancing with the Stars Finale

by at . Comments

Kelly Clarkson is an ABC gal now.

The inaugural American Idol champion premieres her new singing competition, Duets, on that network tomorrow night; and she also stopped by on Tuesday to belt out a medley of the singles "Dark Side" and "Stronger" on the Dancing with the Stars finale.

Look for the music video for the former track to be released this week and then watch Clarkson in action now. This artist can seriously bring it, can't she?
