Kristen Stewart and Robert Pattinson kept apart by studio executives

Kristen Stewart and Robert Pattinson are being kept apart by studio executives who are worried about how fans will react to their rekindled romance.

The couple split in July after pictures emerged of Kristen kissing married director Rupert Sanders and although Robert has forgiven her, the duo and 'The Twilight Saga: Breaking Dawn Part 2' co-star Taylor Lautner will travel to different continents for promotional duties.

Robert will focus on Australia, Kristen is being sent to Japan while Taylor will be visiting Brazil.

A source told The Sun newspaper: "Many of Rob's fans are still angry with Kristen and it has been decided that all three should go their separate ways.

Meanwhile, as Kristen attended the Florence + the Machine concert at the Hollywood Bowl in Los Angeles with her father over the weekend, Robert was in New York with his pal Tom Sturridge and Tom's fiancee Sienna Miller.

The group were spotted at the Monkey Bar and Electric Room on Friday (05.10.12) before Sienna's movie 'The Girl' premiered at the Hamptons Film Festival on Saturday (06.10.12), according to the New York Post's Page Six.
