Robert Pattinson Still Not On Board to Promote Breaking Dawn 1Robert Pattinson has yet to commit to promoting the final “Twilight” movie, Breaking Dawn, Part 2″ overseas because of his unwillingness to be cooped up in an airplane with ex-girlfriend Kristen Stewart, according to a new report.

The latest news comes amid conflicting reports from Twilight studio Summit Entertainment that Rob had agreed to promote the film and appear on the red carpet with Stewart.

The 22-year-old actress and Pattinson, 26, have been on the outs since July when a tabloid photographer exposed her secret affair with “Snow White and the Huntsman” Director Rupert Sanders.

Some reports claimed that Pattinson agreed to appear on the red carpet at the movie’s premiere to prevent Kristen from being booed. But now that seems up in the air.

The situation has caused concern for studio executives because Rob and Kristen, who play lead characters Edward Cullen and Bella Swan, have been instrumental in promoting the films in the past. They have always traveled together along with Taylor Lautner, who plays werewolf Jacob Black.

So far, Pattinson has not agreed to make personal appearances to promote the picture in Madrid, Tokyo or London, “because of the Kristen drama,” a source told The New York Daily News.

If Rob agrees to go, Summit may have to rent a separate private jet to fly the star to the promotional events, so he won’t have to spend time with Stewart.

“Taylor, Kristen and Rob always fly together,” said the source. The film will be released in November. Most of the heavy promotion will take place in October.
