Christie Prody, the ex-girlfriend of O.J. Simpson, claims the former NFL star was obsessed with his ex-wife Nicole Brown to the point where he talked about her every day.

Prody told "Inside Edition" that he would often compare her to Brown and asked her to dye her hair blonde so she would look more like his ex-wife.

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

Prody met Simpson when she was 21-years-old, Simpson was 46. The began dating shortly after he was acquitted of killing his ex-wife and her friend Ronald Goldman.

"I was young and so he could try to shape me, mold me, into what he wanted," Prody said.

She told "Good Morning America" that she tried several times to leave but he would always find her, threaten her and manipulate her into coming back.

Prody, now 38, also said that Simpson would threaten using Brown's name telling her to watch out before "something bad happened to her like Nicole."

She told "GMA" that she believes he did kill Brown and Goldman saying that it took her a long time to realize and face the truth.

Prody broke up with Simpson in 2008 after he was arrested for armed robber in Las Vegas.

Simpson, 65, is currently serving 33-years in a Nevada prison but recently appealed he court's decision.
