Robert Pattinson and Emilie de Ravin: The reason for Kristen Stewart’s cheating?

OHMYGOSSIP — Robert Pattinson‘s friendship with Emilie de Ravin caused his girlfriend, Kristen Stewart, to cheat on him with her Snow White and the Huntsman director Rupert Sanders. Rob and Emilie become close while filming Remember Me in 2009. And sources say Kristen hated their relationship!

“[Kristen] found it difficult to cope with Rob being close friends with another woman,” dished one insider.

“As their friendship grew, she ­became more envious to the point that she would be very upset. They struck up their friendship when they were working away in New York and Kristen was still living in Los Angeles.

“Nothing romantic ever happened between them, but it didn’t make Kristen feel any better about them being so close. They would socialize together away from the set too. They would spend their evenings together in bars and restaurants while they were in New York.”

After news hit that Kristen had cheated on Rob with Rupert, Pattinson, 26, and Stewart, 22, both left the Los Angeles home they shared pre-scandal and are living separately elsewhere

And they’re now avoiding each other.

However, People notes that the duo will likely be reunited soon — they’re scheduled as co-presenters at MTV’s Video Music Awards on Sept. 6, followed by their massive promotional tour for the final film in the Twilight saga, Breaking Dawn: Part 2, due out Nov. 16.

Meanwhile, it’s been claimed Rob told Kristen that she “completely humiliated” him by cheating.

“Rob is devastated and deeply hurt,” a source said.

“They spoke on the phone and he said ‘You’ve completely humiliated me’. All the trust has gone. Robert wanted the world to know that he hadn’t done anything wrong and that she had made a fool of him publicly. He still can’t fathom why she cheated. Kristen is begging for another chance. Robert is undecided.”
