That's pretty crappy. The bum used a high scope telephoto lens more than a mile away, to invade her privacy. If she was on a nude beach in public, then she wouldn't have room to bitch about it.
Would you care if some creep filmed your teenage girls at a pool party(with suits on, of course), or up your sister/wife's/or your skirt with a cell phone?
I'm not a huge Hollyweird fan, but these idiots go too far just to sell trash.
