Determined not to make the same mistake twice (or more than that, if you don't believe that their affair was one fleeting afternoon car ride), Kristen Stewart is now rejecting Rupert Sanders' advances.

Radar Online reports that ever since Liberty Ross pulled the trigger and filed for divorce from the 'Snow White and the Huntsman' director that he's been hitting up K-Stew to try to rekindle their fling.

Sources say that Sanders has been emailing and texting the scarlet lettered starlet -- to no avail.

“Rupert’s reached out to Kristen, but she doesn't want anything to do with him,” the insider dished.

“He texted her a number of times after Liberty filed for divorce, however Kristen didn't respond. In truth, she regrets ever getting involved with Rupert, because of how much it hurt Robert Pattinson and the amount of public backlash she was subjected to."

That plus the whole fact that she and Rob are reportedly back together. That may complicate things a bit too, right?

Well, sort of.

“Kristen doesn't really know what’s going on with her and Robert at the moment, and she’s been left in limbo. Ideally, she would like things to go back to how they once were, but that’s proving a lot more difficult than she imagined."

In fairness, that's understandable. It's sort of what happens when you hook up with a married director. On camera. When you have a famous boyfriend. And literally the whole world knows about the whole mess.

Still, even if she and R-Patz are rocky or even over, don't expect a rebound with R-Sands. “When it comes to Rupert, that ship has sailed."

Not only did it sail, it sailed right into a hurricane and may have released the Kraken on her career. Of course if the Razzies are any indication, 'Twilight' did that already.
