According to the URL, it is:
http://www.purehdwallpaper.com/wallpapers/catherine-zeta-jones-bikini-1600x900.jpg
But, if you use the URL to do an image search with Google, it identifies her as Catrin Claeson, a Danish model.
Who the heck looks at the URL? Only a noobie FReeper who’s been living in a cave would rely on such for ID.
We all know (Laz especially) what CZJ looks like.
