Stewart's affair with Snow White and the Huntsman director Rupert Sanders has prompted studio executives to split the three main actors up for public appearances, according to The Sun.
Despite rumours of a reconciliation between Pattinson and Stewart, an insider said they will visit Australia and Japan respectively. Lautner is expected to head to Brazil at the same time.
The source told the newspaper: "Many of Rob's fans are still angry with Kristen and it has been decided that all three should go their separate ways.
"Keeping them apart will mean less chance of reprisals from fans who were devastated by the split."
However, they added: "No decision has been made on the London premiere, which is happening a little later in November."
