Robert Pattinson and Kristen Stewart

Robert has rekindled his romance with his ‘Twilight Saga: Breaking Dawn Part 2’ co-star despite her fling with married director Rupert Sanders and although it took his siblings Lizzy and Victoria some time to move past Kristen’s betrayal, they have decided to forgive her for their 26-year-old brother’s sake.

A source told "It was really important for Kristen to win back the love and trust of Rob's family, and she has done just that.

 "They are all back on really good terms -- even better than before. Kristen reached out to Rob's sisters and expressed how sorry she was. They are proud of how far she has come and they know she has been treating their brother like gold."

It was recently revealed Kristen, 22, is set to star in a sequel to ‘Snow White And The Huntsman’, the movie on which she met and fell for Rupert but he will not return as director as he is still trying to save his marriage to Liberty Ross.

A source said: "The script has already been written and production will begin late next year.

"However, Rupert Sanders definitely won't be a part of the project. Rupert didn't want to be a part of it to begin with because he is desperately still trying to save his marriage. The search is still on for a new director."
