And so the Kristen Stewart soap opera trundles on, turning out to be far more interesting than all of her movie roles put together.

Now Robert Pattinson has allegedly moved out of their LA home after his girlfriend 'completely humiliated' him by having an affair with director Rupert Sanders. There's obvz just not enough room in their mansion for the two of them. He's told her that he 'needs space'. Sources close to the actor say that Robert was the one who actually called for her over the top apology in the first place. ''Robert wanted the world to know that he hadn't done anything wrong and that she had made a fool of him publicly... 'He still can't fathom why she cheated. Kristen is begging for another chance. Robert is undecided.''

Meanwhile another source - according to The Sun - says Rob is both "heartbroken and angry", adding: "I'm not sure they'll be able to recover from this."

What's more, Kristen now apparently wants to write a full grovelling letter of apology to Rupert Sanders' wife - Liberty Ross - which we can guarantee will go down like a lead balloon. Sources say "Kristen is going to do the decent thing and write Liberty a private letter expressing her deepest regret for her actions... Kristen feels she made a terribly naïve ['naive' my HOOP] mistake and will do anything to make amends. The fact that Liberty and Rupert have two kids has now dawned on her and she feels awful."

Want our advice? Just leave it out, Kristen. This is getting faaaar too big for you to handle. And who does your PR? Haven't they heard of crisis management? Say as little as possible, isn't that the golden rule?

Besides, you didn't feel so awful and it wasn't such a 'momentary indescretion' when you took Ross and Sanders' kids for ice cream two months ago. (The Daily Mail report that she'd been doting over the kids during the press tour for Snow White). And those pictures of you cosying up to your director were taken BEFORE you took the kids out out so now we're not sure what to believe at all. Now we think the affair might have been going on longer than you initially made out. Hmmm...

As for how this will affect their forthcoming movie releases? Given the backlash on Twitter, Hollywood bosses have decided to hold off on a Snow White sequel for the time being but as per analyst Paul Dergarabedian, the last installment of Twilight should still do just fine, maybe even better. Which might lead some skeptics to consider that underneath it all, this could be viewed as one big publicity stunt. “Fans think of Bella and Edward and Kristen and Rob like family... There's a soap opera going on off-screen, and people love to follow that."
