New 'The Voice' mentor Kelly Clarkson is making the rounds on national TV before her tour kicks off. The singer performed her two empowered singles from her latest album 'Stronger' on 'Saturday Night Live' last night (Jan. 7) and she ripped the roof off, courtesy of her powerhouse pipes.

With her brown hair blown stick straight and heavy bangs covering her forehead, Clarkson looked nothing short of amazing. She shined in a shimmery, sequined tank top and black pants as she laid down her hit 'What Doesn't Kill You (Stronger).' Clarkson was bouncing around her mic stand and enjoying herself as she delivered the song. Her voice was soulful and powerful as usual as she commanded the 'SNL' stage with both her band and her backup singers. All eyes were on her.

Clarkson returned to the stage for a rendition of 'Mr. Know It All,' which ended up becoming somewhat of a sleeper hit through the fall. Like any pop diva worth her salt, she swapped outfits, this time wearing a cute, form-fitting pink leopard print dress with her hair pulled back in a ponytail. It's clear that Clarkson is in her element when she is on the stage, grooving with her band and smiling. Her voice is undeniable.

If you fell asleep early or were out late last night, you can watch both performances below.
