Ash, I don't know for sure which pics you are referring to, but those of her in the bathing suit are obviously from months ago, and very well just prior to June at the time her hair looked like that. We have seen a pic of her more recently from that photo collage that was posted on her mother's facebook page. Her hair looks quite different from how it did in May and June 2013.
Are there other photos being posted on tabloid sites of her looking like she does now based on the photos that were on her mom's facebook?
If so, then yes, they are being leaked, but still that does not mean Paris is doing it or posting any pics of herself on a public account. I hesitate to believe any of these instagram accts, etc, are actually hers, but are most likely posers...and as so often, believed to be her by many fans.
As far as all these articles that have been picked up that are based on one article where obviously someone sitting in a writer's chair working for a tabloid, knowing the interest nowadays on Michael's daughter, and needing to come up with a hot article quick (maybe a deadline...) and having no scruples plus having the go ahead to lie anyway whenever deemed necessary, they saw the bathing suit pics and said to themselves:
"Oh, yes, baby, now we got something...buzz is Paris (might be) in Hawaii with bros...here she is in a selfie with a bathing suit (oh, now that I look more closely that is probably from awhile ago...ah, people are stupid; they'll buy it) and how perfect that.. well, who doesn't immediately associate an Hawaiian Vacation with wearing a Bathing Suit! Yep, got me a story to stretch and fabricate here! BINGO!"
Not so hard to get into the head of one of these tabloid writers, now is it? (embarrassingly enough)
I do not know who is leaking the photos. If intentional, how sad. If unintentional, I hope they learn from this and proceed with more wisdom. A celebrity cannot control everyone around them, and I know that Paris is a child of a celebrity, unfortunately, now she is viewed as one, and has been made into one, by the media. The line has been already crossed. In this season of time, the high interest is established.
