She’s known for her ability to captivate an audience, and last night (May 20) Kelly Clarkson graced the 2012 Billboard Music Awards with a fabulous live performance.

The “Since You’ve Been Gone” songstress hit the MGM Grand Garden Arena stage to sing her new single “Darkside” for the first time on network television.

Clarkson looked amazing in a red cleavage-baring floor-length dress as she flawlessly belted out her new song.

Prior to the gig, Kelly tweeted, “Just finished rehearsing for the Billboard Awards! Looking forward to performing my new single tomorrow for the show!”
