The pair recently filmed 'The People v. O.J. Simpson: American Crime Story' together, in which Cuba stars as O.J. while John plays his lawyer Robert Shapiro, and the 48-year-old actor says his co-star kept him entertained on set.

He told PEOPLE: "John Travolta is my favorite co-star of all time.

"Besides singing with him to entertain the gallery of the courtroom, I just enjoyed hearing stories of his life from [sitcom] 'Welcome Back, Kotter' to travelling with Michael Jackson."

Meanwhile, Cuba previously admitted he thought he was having a "nervous breakdown" while filming the TV show.

Cuba plays the disgraced American footballer and recalled how he "couldn't stop crying" when he filmed one scene where he has to kiss the face of the late Nicole Brown Simpson, Simpson's wife who he was found not guilty of murdering, while she is in her coffin.

He said: "I had to rush out to my trailer, I just could not stop crying.

"I realised it was because, in real life, rooting for O.J., I had never acknowledged the victims.

"We had even gone to church to pray for Johnnie Cochran to get OJ 'out of his predicament'!

"I thought I was going crazy, having a nervous breakdown."
