There were reports doing the rounds that the two exchanged "few angry words" during the shoot and have been giving cold shoulder to each other since then.
Hathaway's representative has slammed the rumours calling them "rubbish" and "false," reported E! online.
"It's complete rubbish and totally false. Everyone on the film is having a blast with each other. So typical that a tabloid would pit females against each other. It's sad. They don't do this with men," the Oscar winner's representative said.
