Song Help

Hey, I'm dieing to figure out this song title. I was shopping at Kohl's today in the Juniors section and heard this song about a girl not being that girl anymore. She was just saying how her ex-boyfriend is gonna miss her and that shes changed and stuff. I cant exactly pin a direct lyric sorry. But the main part is how shes not that girl anymore. It was more between pop and rock.

Maybe its a rock version of Wicked - I'm not that girl

It is Kandi by One Eskimo. It is like a duet with the chorus singing "He called me baby, what did he do, He called me baby all night long."
