any ideas? "not your girl"??

Hi!
I heard a song on the radio and I really liked it - but of course the presenters didnt say what/who it was.

All I know is that it is dance.. and 1 line in the song was " Im not your girl" or " I aint your girl"

sorry its not too much to go on, but and ideas would be much appreciated.

I believe it to be a recent song and it was sung by a female. From what i can remember it was more music that vocals.

thanks

Maybe "I'm Not Your Girl" by Lalaine, or "Sorry, But I'm Not Your Girl" by K-Sonix.
Good luck!
