I'm not trying to be annoying, but the reports of Rob not showering are not true.  Rob, being the dork that he is, actually started the rumour himself.  He was on a talk show (Jay Leno)  and made a comment about never showering.  The comment went viral over the internet.  Whenever someone alleges that he doesn't shower, it's always "a source" and never a real person.  Peter Faccinelli & Kellan Lutz actually came to his defense and said the rumours were false.  And you have to take into account the fact that Kristen Stewart, being the strong person that she is, would never allow him to do the intimate scenes with her if he smelled bad.  She would definitely tell him off.  Sorry, I just feel compelled to come to Rob's defense when I hear stuff that's false.
