Millions of people had their worlds rocked when the news broke about Kristen Stewart cheating on Robert Pattinson. Now, she attempts to explain why it even happened.

The big question on every 'Twilight' fans mind was, why? Why would KStew cheat on RPatt with some old guy? This video offers a possible explanation for the whole mess, and thank god for that.

Kristen Stewart at least owes us that. Why would you break up Bella and Edward? How could you do that to the world? According to this video, it's because Rupert Sanders sleeps with his actors in order to better get to know them, and it also relaxes them on the set. Oh, okay. Now we get it.
