Two friends sat down to have an open, long and honest discussion. However, things took a turn when Cheadle’s age was brought up.

The internet decided the moment should live in infamy and many Twitter users shared the exchange and added their takes.
Hart stated that Hart to Heart would have no pre-production, but there was some preparation when Hart accidentally offended Cheadle.
Cheadle was talking about his hopes of becoming a jazz musician, as well as his private life. He casually mentioned his age. Hart revealed to Hart that Hart was 56 years old. Hart responded:

“Damn!” which was followed by an awkward silence, and a hard stare.
“I’m sorry,” Hart quickly said, “I’m sorry. It was just a thought, and I blurted it out. It was not what I meant.”

Hart was told by Cheadle that it’s fine, he’s fine, but the tension in the studio can be cut with a knife. They then discussed Hart’s “damn” tone and whether it was complimentary.

Although the tone of the interview seemed to be dropping dramatically at this point, it was still a very close interview. Hart shared a clip from their interview via Instagram and said that Don Cheadle and Hart can be seen doing what is best for them on the show, followed by four laughing emoticons.
