Twilight co-stars Kristen Stewart and Robert Pattinson, have reportedly ended their three-year romance, because their schedules were too busy.
The couple, who began dating in 2008, have been finding it difficult to make time for each other.
According to Now Magazine, a source said: "They both have hectic work schedules, Rob in particular,"
"Their phone calls were getting fewer and further between."
"They started to only see each other on set and began to drift apart until a general apathy developed."
"There have been a few tears but the pair remain friendly."
A spokesperson for Pattinson declined to comment to Now Magazine last night.
