Nathan recently told the Daily Star: "One of the songs is about Ariana. She hasn't heard it yet. Knowing Ari she'll corner me the next time we bump into each other and demand I play her the song." Not in a bad way, that is.
Nathan reinforced that "It is a nice song. She has nothing to worry about. I'm not scared of her reaction. It's very complimentary and emotional actually. She will hear it and think 'Oh so you do have feelings.'"
So, no ex-girlfriend bashing here, but we have to admit, Nathan writing a song about a famous former girlfriend will likely get plenty of ears on it. Who else is curious to hear what he has to say about Ari?
