Los Angeles – After months of speculation, Khloe Kardashian is ending her four-year marriage to Lamar Odom. The reality TV star filed for divorce yesterday in the Los Angeles County Superior Court, citing irreconcilable differences. The filing comes days after Odom pleaded no contest on Monday to a misdemeanour drunken driving charge. The 34-year-old athlete was arrested last August after his Mercedes-Benz SUV was seen weaving on an LA freeway. He seemed to address rumours of personal problems when he tweeted a cryptic message in September, saying he had been “Seeing the Snakes”. Only the Kardashian family, Odom said then, was standing by him. The 2m power forward has been out of the NBA since going unsigned as a free agent after a miserable season last year. TMZ first reported the divorce filing.
