Could things get any worse for the actress? Actually... yes.
According to OK! Weekly, Stewart reportedly reached out to Rupert Sanders and briefly dated him long after news of their initial affair came to light.
Sources say Stewart and Sanders rekindled their romance after his divorce was finalized, while she was still trying to work things out with Pattinson, only for the director to finally pull the plug for good.
Liberty Ross, meanwhile, allegedly found out about Kristen's extended relationship with her ex-husband and "left a message" for her, the magazine claims.
The message "suggested she might as well sew a big letter ‘A’ on her chest, since she’s never really apologized to the now divorced mom," says an insider, referencing The Scarlet Letter.
Stewart did famously apologize to Rob soon after news of her cheating went public, but it sounds like she never made the same mea culpa to Ross. Should she have? Does she owe the model an apology?
Or should Liberty reserve her furor for Sanders, the man who actually stepped out on her and their kids?
