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