http://blastr.com/2011/11/rumor-of-the-day-edward-c.php Now magazine's source says that while visiting the set of Snow White and the Huntsman, Pattinson "started mocking the Thor star's Aussie accent," and next thing, "They had to be pulled apart." Would pay everything I have to see Pattinson either blown out an airlock or blasted by the god of thunder. Take your pick.
While I doubt the story is true, if it is, we might find out if Pattinson's teeth sparkle in the sun.
As much as I despise Twilight, some young Australians can be really young, obnoxious, load and rather annoying. There's a lot of them around the Putney/Fulham area where I live. I probably would've mocked the accent as well.
