Emilie and Rob's kissing scenes were very exciting.

Did the pictures of Robert Pattinson and Emilie de Ravin rolling around in the grass and kissing during the filming of "Remember Me" spark jealousy inside Kristen Stewart that later caused her to cheat?

Stewart was caught cheating with her "Snow White" producer Rupert Sanders recently and has apologized to everyone involved, but Rob has moved out and the two may be headed for a split.

Now a new report cited by the Christian Post cites a new source who "has revealed that Kristen Stewart may have cheated on Pattinson, her boyfriend of at least three years, because she felt threatened by his relationship with Emilie de Ravin.

The source says that there was no cheating or inappropriate relationship between Rob and Emilie, but their closeness was too much for the US actress.

The film is two years old, so this sounds like a really big stretch of a poor excuse.

Rob and Kristen will re-unite…

Because they have to. RPatz will reunite with KStew for the premiere of the final 'Twilight' movie.

The 26-year-old actor has told friends he does not want to "see or speak to" 22-year-old Kristen after her fling with her married film director.

But the 'Twilight' co-stars - who play couple Bella Swan and Edward Cullen in the film - have been told by producers they must attend the November premiere of 'Breaking Dawn Part 2'.

They are contractually obliged to be pictured side by side on the red carpet.

A source told The Sun newspaper: "RPatz is in pieces but the 'Twilight' love triangle storyline is nothing without him and Kristen. It is eating him up that he has no choice but to see her again because of work. His humiliation is total."

Robert moved out of the Los Angeles, California mansion he shared with Kristen after he discovered her affair with father-of-two Rupert.

The couple had been together for three years and both Kristen and Rupert - who met on the set of 'Snow White and the Huntsman' - have publicly apologized.
