Latest rumour claimed that Hollywood's controversial couple Robert Pattinson and Kristen Stewart broke up as the British actor will head to Australia to film his upcoming movie, "The Rover".

The actor confirmed that he will be heading down under in a few days ready for his new movie, leaving his girlfriend behind. The couple, who were spotted at a Golden Globe after party on Sunday night after the British hunk presented an award at the event, are set to be separated while Rob films 'Rover' in Australia for the nine week shoot.

Despite leaving his girlfriend in Los Angeles alone, Rob admitted the role was "fun" and "cool" "It's set 20 years in the future, in Australia," he said.

"Basically, I'm an American whose brothers are in a criminal gang in Australia. Guy Pearce's character kidnaps me to try and find my brother. Other than that, it's really complicated. But it's cool. It's really fun."

This rumour was in line with the previous reports that claimed Kristen Stewart is trying too hard to regain Rob's love and attention and the "Cosmopolis" star started to feel suffocated with Kristen's actions.

The break up rumours was fuelled by Rob's attending the Golden Globes 2013 solo.However, Kristen joined her beau at the private Golden Globes after-party after the awards ceremony.

Hollywood Life quoted a source claiming, "Things with them aren't good. They've been fighting a lot. Rob isn't happy. It's just a matter of time before he ends this... Rob is at a point where he sometimes ignores her. He'll go out and won't respond to her calls or texts right away. Things will be strained for a while. She knows she has to go along with it. She is working hard at the relationship."

The couple's relationship "will be truly tested when they are forced to spend long periods apart on different film sets in the near future. If they are able to work out being apart while Kristen is filming then they have a shot," the source added.

The couple's relationship was put in jeopardy when Kristen Stewart's cheating scandal broke out summer of last year. Kristen had a scandalous affair with her "Snow White and the Huntsman" director Rupert Sanders. However, Robert Pattinson graciously forgave his girlfriend.
