After all that hooplah about Kristen Stewart cheating on Robert Pattinson with director Rupert Sanders, how could the two Twilight stars be getting back together already?

Perhaps it has something to do with the nature of Stewart's philandering ways. Apparently, she never really got busy with Sanders like that.

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

Okay now, serious question, is that even cheating? Just kissing? Let us know in the comments section, please.
