Ah now, this is just plain mean. Or genius. Will Ferrell ordered an intern to ask Kanye West to turn down his 'art' while on the Anchorman 2 set. That's like shooting fish in a thimble.

Speaking on The Jonathan Ross Show (the less said about Woss's frighteningly kack British Comedy Awards intro monologue the better...), due to air tonight on ITV, Will 'you just can't get enough of me' Ferrell said: "It was very surreal to have Kanye - who's such a big fan of comedy - in our movie hanging out for two days. He was playing the new tracks a lot - over and over. Even when you're trying to film, he's playing the tracks. They're loud too. We got a scared 18-year-old intern to ask him to turn them down."

The cast - including Paul Rudd, Steve Carrell and James Marsden - and crew were apparently shocked by the hip-hop star's erratic behaviour and were too scared to ask him to keep quiet themselves.

An on-set source told the Daily Mirror: "Kanye made a total nuisance of himself. He gave it the big 'I am' even though he filmed a blink-and-you'll miss it cameo. When an intern asked him to turn the music down, he barked back quite aggressively."

It appears the 36-year-old rapper fully enjoyed his time on set, however, since he declined to leave even after his scene was wrapped. Will added: "He hung out, even after we said, 'You're done.' He was like, 'No, no' and stayed in the background hanging out and fighting with people."
