Apparently Perez forgot Miley Cyrus is still a minor and thought it would be appropriate to post an up-skirt photo of her getting out of a car on his blog. He's since taken it down and posted a poorly conceived and flippant faux-pology in which he both denies having done it but contradictorily asking if we really think he's that stupid (well, yeah, I do). You can read more about it and see his apology without going to his site here.
I hope he's prosecuted and at the very least has to issue a sincere apology and pay a fine. Jail time would work for me too though. He's a nasty little vulture.
