America’s OK magazine has claimed that Kristen Stewart has dumped her Twilight co-star Robert Pattinson after he got too serious, too quickly.

“Rob was talking marriage,” an insider told the magazine. “The relationship was also stealing all of Kristen’s attention and keeping her from spending time with her friends and family.

“She told him they need to take a break.”

The pair are currently filming New Moon sequel Eclipse in Vancouver, Canada. They are also thought to have disagreed about where to live when filming had wrapped. Pattinson reportedly wanted to avoid Hollywood, whilst Kristen wanted to remain in LA.
