Will.i.am has left BBC bosses unimpressed after swearing during Saturday's live semi-final show.
According to The Sun BBC bosses have since stepped in to give the Black Eyed Peas star a 'dressing down' after he told contestant Cleo Higgins: "To have to go through the public and things on iTunes - that s*** - that stuff is really hard to swallow."
Realising his mistake Will.i.am immediately apologised for the slip up but that was not enough to appease bosses who are keen to uphold the show's family friendly reputation.
A source on the show has told the press Will.i.am has been "taken to one side and explained it can't happen again".
