Kelly Clarkson first CD in over two years when Stronger hits store shelves and online retailers on October 24th. Like with any other musician who wants to entice the public into buying their new album when it comes out, Kelly hit the talk show circuit which included a stop on The Ellen Degeneres Show earlier this week.

Supported by a full band and a few backup singers and wearing a form-fitting dark grey dress, Kelly proved she still had the voice that won her the first American Idol crown in 2002. Along with a performance of her new single, "Mr. Know-it-All", Kelly also belted out a rocking rendition of her hit "Since You've Been Gone". Check out both performances below.
