It's the glitter queen herself, Kesha (formerly stylized as Ke$ha)!
The 27-year-old entertainer has a very unique style that can seem kind of outlandish, but she's so damn hot that we don't really care. While she's mainly a synthpop artist, a lot of her music encompasses other styles. The fact that she's inspired by artists like Madonna, Queen and Beck just make her even more awesome.
"TiK ToK." was our guilty pleasure in 2010 and was probably responsible for a lot of the regrettable decisions we've made. And for that, Kesha, we thank you.
