Simpson, who lives in the Miami suburbs, also told WTPS-AM the reported advance payment figure of $3.5 million was inaccurate. Although he would not specify how much he was paid, he did say it was a "windfall" that would go mainly to pay bills and support his children.

"Would everybody stop being so naive? Of course I got paid," Simpson said with a laugh. "I spend the money on my bills. It's gone."

Simpson's interview came two days after News Corp. chief Rupert Murdoch canceled the book and two-part interview that had been set to air Nov. 27 and Nov. 29 on the company's Fox TV network. All copies of the book will be destroyed, officials with publisher HarperCollins have said.

The cancellation came amid an intensely negative nationwide reaction to what was being billed as a thinly veiled confession by Simpson to the 1994 murders of his ex-wife, Nicole Brown Simpson, and her friend Ron Goldman. Simpson was acquitted in 1995.

In the Miami radio interview, Simpson was asked point-blank if he killed the pair.

"Absolutely not, and I maintained my innocence from day one," he replied, adding a little later: "No matter what everybody wants to say, I didn't do it."

Simpson also said he told the writer, "I have nothing to confess."

As for the "If I Did It" title, he added: "That was their title. That's what they came up with. I didn't pitch anything. I don't make book deals."

Simpson also accused the Goldman family—which won a $33.5 million civil wrongful death judgment against him—of "opening up those old wounds" on frequent TV appearances.

"It happens every month to me. Everybody's calling me names," Simpson said.
