It not easy being the heavyweight champion of the world.Anthony Joshua is a man in demand after defeating Carlos Takam to retain his WBA, IBO and IBF heavyweight titles and it seems as though he is destined for a huge 2018.Whether he makes unification fights with either WBO champion Joseph Parker or WBC champion Deontay Wilder, or even an all-British scrap with Tyson Fury, they are all huge box office fights.But it seems as though the Watford-born champion has been making the headlines for all the wrong reasons lately.After getting into Twitter wars with Tyson Fury and Kugan Cassius, Joshua uncharacteristically used expletives to address his rivals with Cassius claiming that is the "real Joshua."However, things went a step further earlier this week when American heavyweight Eddie Chambers leaked some seemingly racist messages from AJ's Instagram account.Joshua allegedly sent Chambers a message calling him a "Disgrace to the superior black race! F*** u."

Joshua's promoter Eddie Hearn initially denied Chamber's claims and said it was a fake account, but now Joshua's camp have accepted that it did indeed come from the champions official Instagram.

However, Daily Mail reporter Riath Al-Samarrai has revealed that Joshua's camp are saying the 28-year-old was hacked and he did not send those messages.

Joshua is currently away in Dubai enjoying a break and has not personally made a comment on the matter as of yet.

It would certainly be a strange thing for Joshua to say on numerous levels, but given that Hearn's initial reaction was that it was a fake account - when it clearly wasn't - it suggests that the Matchroom Boxing king wasn't fully aware of the situation.

If that is the case, chances are Joshua wasn't either. Also, you'd imagine a world champion boxer is well aware in this day and age that any messages sent can be screenshotted and posted online.

No fans are really clamouring for Chambers to get a fight with Joshua regardless, but the longer details of this scandal remain cloudy, the more damage it could potentially do to Joshua's reputation.
