Kim Kardashian may be facing backlash for her short-lived marriage to Kris Humphries, but new reports allege that it was actually the basketball star’s mean behaviour that led to the split.According to US magazine, the breakdown of the relationship was in fact down to Kris Humphries and his mean behaviour.It has been claimed that the 26-year-old former New Jersey Nets player not only neglected his new wife, but he made a series of derogatory comments and is accused of referring to Kim’s famous sizable derriere as ‘fat ass.’“He belittled her in front of people. He’d call her stupid. It was truly sickening,” the Daily Mail quoted a source as telling the publication.“He tried to control Kim by bringing her down... He would say truly terrible things. One time, he said she had no talent and her fame wouldn’t last,” the source added.It is also been alleged that Humphries is planning to sue Kim for $10 million for allegedly being underpaid in one of her shows.“He’s claiming his role on Kourtney and Kim Take New York is bigger than he was told, and that’s why he wants more money. But Kris is also suing because he’s really worried about how badly he’s going to be portrayed on the series,” according Life and Style magazine.The trailer of the upcoming series shows a furious Kim blasting Kris for his partying ways and asking why she found out he wasn’t even in the country through Twitter.Kim’s sister Kourtney is meanwhile, offering her distraught sister relationship advice suggesting the marriage was over before it ever really began.In the wake of their split both kept a low profile and Kim cut a trip to Australia short before visiting Kris in his hometown.While Kris cancelled personal appearances, he did step out as the face of a watch brand, cashing in on his heightened fame.
