Jay-Z and P Diddy argue at Film Festival party

Rappers Jay-Z and P Diddy reportedly had a “huge” backstage bust-up after Diddy tried to take over DJ-ing duties during a bash at the VIP Room nightclub.

Diddy — real name Sean Combs — was keen to get on stage to DJ and entertain the clubbers — but Jay-Z didn’t want him stealing his spotlight.

A source said, “They had a huge long row backstage.

“Diddy wanted to get on stage to DJ and entertain the clubbers – but Jay-Z didn’t want Diddy to steal all the spotlight.

“Jay-Z was shouting at Diddy, saying, ‘No way man, no way.’ and Diddy was shouting back – it was a nightmare for the organizers. In the end, they agreed to both go on stage together and sing New York, New York.”
