They were once close friends, but grime MCs Wiley and Dizzee Rascal have not spoken in over a decade, although no one knew the cause of their argument.
Now, however, Wiley has revealed the reason for their falling-out - and it's a pretty legit one, in Dizzee's case.
The rapper told Time Out that their beef originated on a holiday to Ayia Napa, during which Dizzee Rascal was stabbed as a result of intervening in a fight.
"Basically, me and Dizzee went out one night and there was some fighting with another crew - I won't say who, but basically everyone knows," he said. ""Then the next day, I decided to carry it on - I didn't pull out a knife, I was just fighting. Well, after we started it up again, those guys came looking for us - but the person they found was Dizzee."
He added: "The thing we done the next morning led them to go looking for us, but see him and stab him.
"Now I'm older, I can see: Dizzee in his head will always be thinking: 'I know we got into a beef. I know something started. But you lot carried it on the next day. If you had left it I wouldn't have got stabbed.'
The rapper - who was 19 at the time of the incident - was hospitalised with 6 stab wounds after the incident, which occured the same week he released his Mercury Prize-winning debut album 'Boy in Da Corner'. He has, over the years, admitted that he was partially responsible for the incident - but the wound between him and Wiley has yet to heal.
At the time, a member of So Solid Crew was arrested and questioned about the incident, but later released by Cypriot police.
