Former O.J. Simpson lawyer Robert Shapiro appeared on Megyn Kelly's Fox special on Tuesday night, and finally revealed what his client whispered in his ear after the verdict was read.

"You had told me this would be the result from the beginning. You were right," Shapiro says Simpson told him in 1995 after he was acquitted of the murders of ex-wife Nicole Brown Simpson and Ron Goldman.

Shapiro appeared on "Megyn Kelly Presents" Tuesday, which also featured interviews with presidential candidate Donald Trump, "Rocky Horror Picture Show" star Laverne Cox and Michael Douglas.

The lawyer also discussed the pivotal moment in the courtroom when Simpson tried on the bloody glove. Shapiro told Kelly that he had tried on the glove himself and immediately knew it would not fit his client.

"I want you to walk as close to the jury as you can, hold up your hand like you're carrying the Olympic torch, and pull and tug on that glove," Shapiro told Simpson. "Because it will not fit."

"And clearly it didn't," he said.

Simpson and the murder trial have returned to the cultural consciousness recently thanks to FX's miniseries "People v. O.J. Simpson: American Crime Story" and the eight-hour ESPN documentary series "O.J.: Made in America." In the former, Shapiro was portrayed by a heavily made-up John Travolta.

Shapiro wouldn't discuss whether or not he believed Simpson to be guilty, telling Kelly that he hasn't talked about it with anyone — including his wife.

"There's moral justice and there's legal justice. And when that not guilty verdict, uh, was rendered, I felt legal justice was done," he said. "As far as moral justice, I haven't discussed it with anyone, including my wife."

Shapiro's former client was later convicted of armed robbery in 2008, but the lawyer said he wouldn't have taken on the case even if Simpson had called.

"He still owed me money from the first one," he explained.
