for the first couple of years post nickelodeon she did end up straining relationships with people because she wouldn't be seen with them in public if they didn't fit the image and narrative she was trying to tell. not that she ever said that out loud, it was more like not so subtly suggesting they only hang out at her house and stuff, so if they were close at all during the nick days, diana may have been a victim of that unfortunately. with maturity came the realization she was putting her reputation above the real, legitimate relationships she had in her life though, so maybe sometime recently they reconnected? at some premiere or party or something with a conversation somewhere along the lines of "hey! you have a drink in your hand now!" "yeah! i stopped being such an uptight bitch about my image!" or you know. something more genuine?
