AceShowbiz - Movie bosses have blasted reports Robert Pattinson and Kristen Stewart have fallen out on the set of the next "Twilight" film, insisting there has been "no row or ill feeling" between the pair. The rumored real-life couple has been reshooting scenes for "The Twilight Saga's Eclipse" in Vancouver, Canada.

Insiders claimed Pattinson delayed a shoot so he could stay in his native London - leaving Stewart furious. A source told New York Post gossip column Page Six, "Robert turned up later on the set. When Robert arrived, he and Kristen started fighting. She accused him of taking a later flight from London because he had been hanging out too late at a burlesque bar. He didn't take it well. They were both so angry, the crew had to take a break for an hour for things to simmer down."

But a spokesperson for Summit Entertainment, the production company behind the hit films, has dismissed the claims - insisting all is well on-set. The rep tells Page Six, "Rob was not late on set, he arrived later because (he) had a different call time than other cast members. There was no row or ill feeling at all. Everything went very well."

It isn't the first time movie chiefs have had to reassure fans about the film - last month bosses dismissed rumors they weren't happy with the final cut after a number of reshoots. The movie is due for release in June.
