Is Selena's song for Demi?

Their friendship may be "on a break" right now, but that doesn't mean Selena has stopped caring about Demi. In fact, Selena has told M in the past that Demi's struggle with bullying is something that weighs heavy on her heart. Selena gets that Demi, and millions of other girls, go through issues like that-which is why she chose "Who Says" as the first single on her new CD. "Basically it's to the haters trying to bring you down," shares Selena. Lately, Selena herself has experienced bullying because of her new love with Justin-yet another reason this song is so personal to her. "Twitter and Facebook are really negative for me," says Selena. "So this song really touched me when I heard it."
