Kelly Clarkson rocks out with flash mobs

Flash mobs just found a new theme song, courtesy of the just-released video for Kelly Clarksons latest single, Stronger (What Doesnt Kill You) her second single off Stronger.

Like some of her previous vids, the clip is half Clarkson on a stage, full attitude with the microphone, sassily walking around singing her story.

The other half explains how shes been wronged: In this case, the story is essentially a giant It Gets Better/Cant Hold Us Down dance-off the world over. Everybody is getting stronger all over the place and whether its an exercise class, the beach, or Times Square, its the perfect place to let loose and move on. Its Since U Been Gone round two. Clarksons got your back.

Watch the video below:

My favorite part may be around 2:50, when Clarkson ditches the studio and the band and joins her fans for an old-fashioned dance party. Her goofy expressions plus that karate chop remind me why Ive always loved her.

The awesome new vid isnt the only great news for Clarkson fans. It was just announcedshell also be releasing a nine-track iTunes EP session on December 27th, which will include reimagined versions of some of her biggest hits, as well as Christmas track, Ill Be Home for Christmas (which is available for download now).

Readers: Who else wants to leave their cubicle and start dancing with Clarkson?
