They hit headlines in July 2012 after their affair became public. The actor-director duo met on the sets of 'Snow White And The Huntsman', reported Sun online.
"Rupert's reached out to Kristen, but she doesn't want anything to do with him. He texted her a number of times after his wife Liberty (Ross) filed for divorce, however Kristen didn't respond," a source said.
"In truth, she regrets ever getting involved with Rupert, because of how much it hurt Robert and the amount of public backlash she was subjected to," the source added.
"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," a source said.
