Sources close to Kristen Stewart confirmed that the actress and Robert Pattinson have broken up-- for real.

A split was first reported last week with the pair ending their romance after spending New Year together.

Despite partying together after the Golden Globe Awards in Los Angeles just two weeks ago, Star magazine claimed that the two have ended their four years of relationship and cited unnamed sources.

According to the insiders, "Rob really wanted it to work but he just felt like the trust was gone. Neither of them seemed really happy and he just thought it was easier to end it for good. He was honest with her and said they had been through so much he hoped they could remain amicable."

The reason behind the split is said to be the old issue of Kristen's cheating scandal that shook Hollywood last summer. The 22 year-old was photographed kissing married "Snow White and the Huntsman" director Rupert Sanders in Los Angeles.

The source of Star Magazine also said that "She is devastated. It's come as a massive blow as they had been making big plans to start a fresh this year. Kristen really thought they had worked through their problems and were now OK."

So far, there has been a myriad of rumours toward the couple. Rob left for Australia for the filming of his upcoming movie, "The Rover". Some rumours claimed that Rob and Kristen agreed on a trial separation and will see how things will go between them during the time apart.

Last January 20, Rob was spotted partying with friends in an Australian pub known as Zhivago in Adelaide. Rob was also seen snapped a photo with some beautiful Australian girls.

Robert Pattinson and Kristen Stewart were notoriously private when it comes to their relationship and has yet to confirm the rumours.
