What is the name of this song!??!?

Ok, this is driving me CRAZY!! I don't know a lot of the lyrics, I just know that there's a girl on the chorus singing "I wanna shake my uh" And on the verses it's a rapper, a different rapper each time (not a Tupac rapper, more like a Flo Rida rapper sound) it just really sounds like a club song...I know this isn't a whole lot to go off of!! But if ANYONE could help me it would be great!! THANKS!!
