What style of dance is this?

Hi, this might be a stupid question but if someone could help me out that would be great! I really love to dance. I love the way it makes me feel and i guess im really good at it, at least thats what my friends have said. But i've only ever taken ballet when i was little, until i was about ten. Now I make up dances in my room to pop songs like Tik Tok and Tonight Tonight and i practice them for hours, just because. I don't show them to other people or do anything with them i just love to dance and practice dancing. Now i've realized that i actually want to take this seriously so i started looking into dance lessons, but idk what style of dance im dancing! I dont think its hip-hop because thats all break-dancing and ghetto dancing. So my question is what style of dance is it for like pop music and the type that back up dancers for Ke$ha and Britney Spears do?? I know that i couldve made this question soo much shorter and for that i am sorry but thanks for your help!
