Yes, that is true that SOME celeberties do it on sole purpose (which is btw nothing but pathetic!) like the attention whores that they are. Fuck me, theyr sad! But I know not all do it though. Theyr just being careless..... 
Also, many of these girls are no diff than the girls on those leaked gf sites, or the average chica. They think that they are better, but they are not. There is a cavalier attitude towards being a slutty buddy, because there are virtually no consequences. It's okay to be a whore, or leak pics---plus the attention.
It used to be that there was a air of untouchability with stars, now with the internets, there is way more transparency---they are only celebs because they are allowed to be---everything else, they are like us...
What has not been discussed is that Disney seems to be the hotbed for future hot chicks who we will see nude---like Miley Cyrus, Spears, and I think there was that HS musical chick...
