Sources close to Kristen, 22, claim she cheated on Rob, 26, because of jealousy over his friendship with ­his one-time co-star Emilie de Ravin. Rob reportedly became close to the LOST star, 30, while filming Remember Me in 2009.

The source said, “[Kristen] found it difficult to cope with Rob being close friends with another woman. 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.”

But as we know, Rob has always been against cheating and he admits to not understanding the act of betrayal. His relationship with Emilie, 30, never grew into anything romantic.

The source continues, “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.”

Emilie, who played Rob’s onscreen lover, said at the time, “[Rob’s] a lovely guy. I read the script three weeks before they started shooting. I flew to New York to test with Rob and we immediately got along. We had instant great chemistry, which is not an easy thing to come by.”
