Boxing promoter Eddie Hearn is usually very cool, calm and collected in front of the TV cameras, and he's one of the greatest professionals around.He can tell you one of his boxing cards off the top of his head, no matter how far away the event actually is.However, that doesn't stop him from being human... and as we all know, humans aren't perfect.Ahead of Fight Camp getting kickstarted, which is a safe way for boxing to resume after the coronavirus outbreak, Hearn was being interviewed on Sky Sports News at the first official weigh-in before fight night.Sadly for Hearn, however, he thought it was just a rehearsal and didn't actually know he was on live TV.After the interviewer turned to start talking to the promoter, he let out a 'charmone mother*****s'... much to the shock of everyone involved.Hearn's face immediately changed when he realised what he had just done and when he realised he was in fact on live television and not just rehearsing.With the original clip of the incident quickly going viral on social media, the boxing promoter had to respond himself on his official account.

Unsurprisingly, that has also quickly gone viral.

Eddie Hearn, you are a legend!

Fight Camp 1 takes place this weekend, with the event being headlined by Sam Eggington vs Ted Cheeseman.

Also on the card is: James Tennyson vs Gavin Gwynne for the British lightweight championship, Jordan Gill vs Reece Bellotti, Fabio Wardley vs Simon Vallily for the English heavyweight title and Dalton Smith vs Nathan Bennett.

Hearn will certainly be hoping fight night goes a lot smoother than his interview did today at the weigh-in, but it sure has provided us with a fantastic and hilarious moment.
