How is she using her? They barely ever speak now. They aren't bff's anymore. :'( Besides Demi and Selena were best friends way before they were famous. Demi would never do that to a old friend.
I don't think Demi used Selena or Selena used Demi maybe Selena just doesn't like to hang around Demi because of the way she acts partying and stuff or maybe like others said they drifted apart it happens....
I drifted apart from quite a few friends through the years.
