Nicole Simpson’s parents are convinced beyond a shadow of a doubt that O.J. murdered their daughter – and they’ve banned him from talking to his two children.

When O.J. phones from jail he isn’t even allowed to say hello to daughter Sydney, 8, and son Justin 6, who are living with their grandparents Louis and Judi Brown. He can only leave messages for the youngsters on the family’s answering machine.

“We believe O.J. is guilty,” Nicole’s mom Judi told a friend.

As the ex-football star’s murder case rages in Los Angeles, Sydney and Justin are out of the spotlight 60 miles away in Dana Point, Calif. The Browns are making sure the children have a normal life and loving environment like they enjoyed with devoted mom Nicole.

Nicole’s mom Judi told a friend: “After what O.J. has done to our daughter, the last thing we want is for him to have his kids.

“Sydney and Justin are better off with us. We love them with all our heart. With us, the kids will be in a caring environment like the one they had with their mother.”

The children have been living with the Browns since the day after the June 12 murders of Nicole and her pal Ron Goldman.

The tragedy has pulled the family even closer together. Nicole’s three sisters – Denise, Tanya and Dominique – have all moved into their parents home to help the kids. And Denise has become a surrogate mother to them, said a family source.

“For now, Denise’s full-time job is caring for the kids. The grandparents have enrolled Justin in karate class and have Sydney taking ballet lessons, just like their mother did when she was alive.

“Sydney’s and Justin’s days are filled with normal childhood activities, such as going to the beach and playing in the sand.”
