Not that you care, butt...

There's another body-double rumor out regarding Natalie Portman.

First there's the Black Swan dancer wanting more credit, and now there is some British girl reporting that it is her backside diving into a chilly loch in Your Highness, not Natalie's. Granted, this is coming from UK tabloid The Daily Mail, so you may want to get out your pillars of salt in order to consume that one.
I don't want to come out unfair, but to me it sounds like these stuntgirls are after the spotlight. :\
