But, according to what is probably our second favorite tabloid story ever, The Juice is definitely obsessed with Kim Kardashian!
"He has several sexy pictures of Kim hanging up in his prison cell from her 2007 Playboy shot and he isn’t shy about showing her picture to fellow inmates,” an insider tells Radar Online.
Simpson, of course, is serving a 33-year sentence at Lovelock Correctional Center in Nevada for a 2008 robbery and kidnapping conviction.
He also almost definitely killed two people in 1994.
Despite being locked up, however, Simpson still follows celebrity gossip apparently.
"She likes black ball players, I am a Hall of Famer - and I still have my Heisman award," Simpson allegedly joked to a friend recently, referencing Kim's ex, Reggie Bush, who had to forfeit his Heisman for breaking NCAA rules.
And Simpson is confident in his chances with Kardashian, despite the likelihood that he'll die in jail and despite her marriage to Kanye West.
"As long as I am in prison, I can’t be with her so Kanye can have her for now," he says. “But when I get out she’s mine.”
Simpson and then-wife Nicole Brown Simpson used to be close to Kris Jenner and her first husband Robert Kardashian, going on multiple family vacations with them in the late 1980s early 1990s when Kim was a child.
So he's known, and apparently admired, Kim for awhile.
"He reads every magazine he can about her and when she is on TV he demands silence from his fellow inmates so he can watch without interruption," the source claims. "He’s even tried to get in contact with her, but so far she hasn’t responded to him."
Simpson may be eligible for parole in 2017. Consider yourself warned, Kanye.
