O.J. Simpson says he's not Khloe Kardashian's dad. The "New York Daily News" reports the former football star made the declaration after a reporter asked Simpson if congratulations are in order following Kardashian's pregnancy announcement. Simpson told TMZ "congratulations to her, but trust me I have nothing to do with it." Simpson added, "I would be proud if I had anything to do with it, but I don't." Simpson and Kardashian's father Robert were close friends. Robert Kardashian was part of the Simpson defense team in his 1995 murder trial. Robert Kardashian died in 2003.
