Kristen Stewart Denies Sex with Rupert Sanders, Shows Robert Pattinson Emails & Voicemail to Prove it

Did Kristen Stewart really sleep with Rupert Sanders?

The actress says no.

After recently reconciling with boyfriend Robert Pattinson, Stewart now claims that she never had sex with Sanders, the director of her latest film, "Snow White and the Huntsman."

According to RadarOnline.com, a source claimed that this is the actual reason the couple has been able to come back together saying, "Kristen and Rupert both told their respective partners that they didn't actually have sex."

The source continued with the following: "Kristen was absolutely steadfast that she only engaged in several make-out sessions with Rupert but never slept with him. Rob didn't believe her in the beginning but as time wore on he accepted her explanation. Kristen has given Rob passwords to her voicemail and e-mail account to prove she has nothing to hide and will do anything to get his trust back."

Earlier this month, Pattinson and Stewart got together for a face-to face talk to start their amends, which seemed to have worked well after she claimed her affair was a "stupid mistake." Pattinson reportedly gave Stewart a reconciliation ultimatum that he wants "marriage."

"Rob told Kristen the only way he can forgive her affair is if she truly commits to him. Rob has been keen to marry Kristen for quite a while and he doesn't want to get back with her unless he knows she means it for life too," a source reportedly told The Daily Star.

The source for RadarOnline.com commented on the future of the couple, saying, "There are still a lot of raw emotions there and time will tell if Rob and Kristen stay together. Rob and Kristen will be promoting the final Twilight movie and it will be very interesting to see what happens after that."

The couple's progress reconciling may be moving along nicely. Stewart was recently smiling for cameras and appeared in good spirits while at Balenciaga's Spring/Summer 2013 show during Paris Fashion Week.
