Selena Gomez's song HeadFirst about Nick Jonas?

Selena just keeps adding fuel to the fire... She claims it isn't about Nick J, but i think not. She didn't deny not recording it, but it isn't going to be on her new album set to release in July this year. The song was leaked and it seems to be a hit on the internet. The video with the song is set above, so watch it and tell us what you think. (:
