Christie Prody, the ex-girlfriend of O.J. Simpson claims that the godfather of reality-star, Kim Kardashian was so obsessed with his ex-wife, Nicole Brown that he mentioned her everyday throughout their relationship and compared her to Brown.

In an interview with Inside Edition, Prody admitted that her 12-year relationship with Simpson was unbearable.

"It was very hard to deal with that everyday, comparing me to Nicole. 'Nicole did this, Nicole did that. You should do this, that's what she did," she said. 

Prody was only 21 when she started dating Simpson. She said back then Simpson was concerned about losing his athletic build.

"He was always worried about that, about gaining weight. Image was the most important thing to him. Being good-looking was important to him. And even more so, the girl on his arm had to be good-looking," she said.

At the time Simpson and Prody started dating, the former NFL player had just been acquitted of Brown's murder, but couldn't stop thinking about her. Prody admitted that Simpson had "charming" ways, but often threatened her life.

"OJ is very charming. He's very charming and he tells you what you want to hear. He's very believable," Prody said. "He would say things to me like, 'You better watch out so something bad doesn't happen to you like Nicole,'"

Simpson, 65, is currently in prison serving a minimum nine-year prison term. According to reports, he will be in court all week to prove to a judge that he had a team of weak legal representatives in the trial that put him in jail for robbing at gunpoint two sports memorabilia dealers in 2007 in a Las Vegas hotel room.

"He has a very good chance now," Ozzie Fumo, one of the attorneys who represented Simpson said. "I don't think the state was able to counter any of our issues."
