The X Factor wrapped up its season by crowning a champion during its Season 3 finale this week, but we think the biggest winner of the evening was Glee star Lea Michele (Rachel). Lea took to the X Factor stage to perform her first original single, "Cannonball," and we're pretty sure she blew everyone away. 

On December 19, just before Alex & Sierra were named the 2013 winners of X Factor, Lea gave a stunning performance of "Cannonball," her new song that we're growing to love more and more each time we hear it. 

Lea's first-ever live performance of "Cannonball" came last week when she performed the uplifting power anthem on The Ellen DeGeneres Show. And as much as we loved that performance, we think this one is even better, as her stage presence seems even more commanding.

And can we also just say, Lea is basically hotter than we've ever seen her in this video. Like, how amazing does she look in those extra-tight pants? Answer: Quite amazing.

Long story short, we can't wait to buy her full album, Louder. Unfortunately, it doesn't hit stores until March 4, 2014, but judging by how powerful "Cannonball" is, we just know we're going to love the whole thing!
