OJ Simpson appears to be obsessed with Kim Kardashian. He has her 2007 Playboy pictures of her hanging all over his jail cell, according to Radar Online.

"As long as I am in prison, I can't be with her so Kanye can have her for now," Simpson, allegedly told a prison insider who leaked to Radar Online. "But when I get out she's mine."

He still has 33 years left at Lovelock Correctional Center in Lovelock, Nev., on robbery and kidnapping convictions.

He orders magazines that talk about her, watches her on T.V. and has even reached out to contact her, according to Radar Online.

 "She likes black ball players, I am a Hall of Famer - and I still have my Heisman award," the insider told Radar Online he heard Simpson saying to a friend. He was referencing Kardashian's ex-boyfriend Reggie Bush, who had to give back his college football Heisman trophy after it was revealed he was involved with unethical dealings in college.

Simpson met Kardashian through her parents Kris Jenner and Robert Kardashian. He went on several vacations with the family when Kim was a child.

Robert Kardashian also represented Simpson during his 2007-2008 murder trial.

But apparently being friends with her parents isn't stopping 67-year-old Simpson.

"O.J. said he always thought she was a cute girl when she was younger," the source tells Radar Online, "but it has only been since he's been in prison his infatuation with her has grown to a full-blown obsession."
