After marrying off Robert Pattinson and Kristen Stewart and creating a lovely little love nest for them, a US gossip weekly has now decided the relationship is over. What a sad end to rollercoaster of an imaginary tale.

According to the latest issue of OK!, Kristen called things off because Rob - who, at 23, is four years her senior - was getting too serious too soon.

“Rob was talking marriage,” says their source. “She told him they need to take a break.”

The 'insider' explains that Rob was too much of a distraction for Kristen, and kept her from hanging out with her friends.

The prospect of spending long periods of time apart after shooting wraps on Eclipse this week also contributed to the relationship's demise, it's claimed.

Though Rob and Kristen have been spotted looking cosy while hanging out together after hours, the pair have always denied being an item.
