Will.i.am is reportedly upsetting BBC network producers by tweeting as he films The Voice episodes.
The Black Eyed Peas star often posts messages on Twitter via his phone while shooting the hit BBC show.
British newspaper The Mirror reports that Will.i.am isn't impressing bosses with his actions.
"This isn't tolerated whatsoever," an executive said. "We need to show more respect to the people at home. It's like he can't be bothered. This isn't a mickey-mouse satellite channel, this is the BBC where high-production values are key. He's making a mockery of the show."
Will.i.am is thought to be insistent on communicating with his fans while he sits and judges live acts.
"You can't tell Will anything - he's his own man," a source told the newspaper. "He clearly went out there and proved a point this week because he was tweeting more than ever - pictures from the stage too. Bosses are stumped because now they know if they tell him not to do it again he'll do it even more and may even start talking about it."
