Los Angeles: Actor Robert Pattinson and Kristen Stewart are reportedly on the verge of splitting again.
According to America's Life and Style magazine, the two can't stop fighting and friends fear they could be heading for a break-up.
"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," showbizspy.com quoted a source as saying.
Their relationship previously hit a rocky patch when Stewart's intimate photos with 'Snow White And The Huntsman' director Rupert Sanders became public. Stewart and Pattinson split, but they were back together again.
