Will.i.am asked to tone it down after Jessie J row

Jessie J and Will.i.am have come to blows à la Simon Cowell and Cheryl Cole style.

The two judges were fighting it out over talented contestant Joelle, 21, when things got personal, prompting the Black Eyed Peas star to become ‘aggressive’ and require a telling-off from his team.

The pair are reportedly still not speaking to each other following the pre-recorded show.

The feud began when the mentors competed for the wannabe, singing Adele’s Rolling In The Deep.

As Will tried to entice Joelle on his team, Jessie mocks him by chirping: ‘I’m William and I’ve got two dashes in my name,’ to which he retaliates by calling her ‘Little Miss Jessie’.

He then quips: ‘I can’t sing like Jessie but I know how to produce.’

The Where Is The Love? singer admits he grew angry and the situation became ‘uncomfortable’.

Will said: ‘There was one point where my team came in and expressed concerns on the banter.

‘I am the most unconfrontational man in the world, it is not my style, but that was the first time they have ever seen that side of me and they were like, “Will, what are you doing?”‘

He confessed he was ordered into the dressing room and given instructions to chill outDon't phunk with my heart: willi.am is not amused when Jessie J starts pining for the same singer Joelle.

But Will insists the rows are not staged, saying it’s like ‘hungry people fighting over a steak’.

He added: ‘When you are competing and you wanted something and you see Jessie wants what I want, you are a different person and it is hard to control… It is not for the sake of TV.’
