It was initially unclear whether Khan had been hacked as a series of messages from his official Twitter account detailed an apparent split with wife Faryal.
Khan's verified account and a Twitter page purportedly belonging to Faryal duly traded insults and accusations, with the latter said to have "moved up in the weight classes" to see Joshua. Faryal's tweets were later deleted.
Seemingly eager to distance himself from any involvement in the controversy, Joshua responded by tweeting a clip from the video for Shaggy's famous single 'It Wasn't Me'.

Joshua added in a subsequent tweet: "Bantz [sic] aside, I hope you guys can resolve your situation or this is a hack as we have never even met!"
