According to reports, our favourite celebrity couple are 'constantly' arguing over Russell's womanising past. Sugarscape has reported that the arguments often result in the pair sleeping in seperate places and not speaking at all! A source told the New York Daily News: "They fight and make-up constantly. It’s a cycle. "There have always been fights about other women − despite Russell talking about how much he loves Katy all the time."We hope the couple can get over their issues. After all we're looking forward to their upcoming nuptials!
