OJ Simpson's four kids, including his two with slain wife Nicole Simpson, family, and medical staffers were forced to sign Non-disclosure Agreements in his final days, according to a report.

TMZ reports friends and family, who wanted to say their goodbyes to the NFL Hall of Famer while he lay on his deathbed were required to sign NDAs for "privacy" reasons. Approximately 30 to 50 of the 'Roots' actor's friends and associates signed the NDA before seeing him. 

Simpson died on Wednesday at his Las Vegas home after a battle with prostate cancer. He was 76.

The TMZ source also claimed that anyone who was around Simpson while he received hospice care, including medical professionals and staff, was also required to sign the NDA.

Sydney Brooke Simpson and Justin Simpson, his two children with his murdered wife Nicole, were reportedly by his side. The former San Francisco 49ers baller was acquitted in a 1995 murder trial, called the "Trial of the Century," for the deaths of Nicole Brown Simpson and her friend Ron Goldman.

His elder kids from his first marriage with Marguerite Whitley, Jason and Arnelle Simpson, were reportedly with him when he died. Simpson's fifth child, Aaren, drowned in a pool just before turning 2 years old in 1979.

No phones were reportedly allowed in the room with him while family and friends paid their respects.

It's unclear whether the famed running back could speak because, according to reports, he was in and out of consciousness.

His prostate cancer diagnosis was announced in February, where he denied claims he was in hospice. He instead wished everyone a happy Super Bowl LVIII Sunday.
