you wonder who's that chick

I'm obsessed with a song called "Who's That Chick" by David Guetta & Rihanna. I've heard my friend singing it all the time, but I had never heard it until tonight. Tonight was quite an awesome night, and I'm overtired right now. So Imma go get some sleep. "Baby I just wanna daaaaaanceeeee, I don't really caaaaaareeee".
