Kristen Stewart is reportedly adamant that she never engaged in intercourse with Rupert Sanders.

The actress publicly admitted this summer to cheating on beau Robert Pattinson with the Snow White and the Huntsman director.

Kristen and Robert are rumoured to have reconciled recently and may even be living together again.

Kristen is an open book with Robert, as she is committed to winning him back entirely.

"Kristen and Rupert both told their respective partners that they didn't actually have sex," a source told Radar Online.

"Kristen was absolutely steadfast that she only engaged in several make-out sessions with Rupert but never slept with him."

Apparently Kristen is not at all concerned about privacy at this time.

She has provided Robert with access to all her accounts.

"Rob didn't believe her in the beginning but as time wore on he accepted her explanation," the source explained.

"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."
