Does Joe Jonas Miss Ashley Greene?

From source: TheAwfulTruth

Dear Ted:
So I have a question regarding Joe Jonas' new song. Do you also get the feeling he is insinuating Ashley Greene cheated, or am I reading it all wrong? Is it possibly about another ex? For some reason it seems like it's her. Do you have any insight as to why they broke up?

Dear Video Girl:
You may get an Ashley Greene-vibe from watching the vid ‘cause the gal in it looks very Ashley Greene-esque. And while J.J. is cleverly trying to drum up some controversy for the song, à la Justin Timberlake's "Cry Me A River" or any Taylor Swift song, I seriously doubt his heart still needs mending from the twosome's split. Things weren't as serious as they wanted you to believe.
