Kanye West has caused a meltdown over the colour of the linen in his dressing room.

The 'Bound 2' hitmaker allegedly sent staff at London's Wireless Festival into ''pure panic'' over the weekend when they realised his dressing room was filled with black linen instead of his preferred white furnishings.

Festival organisers were sent into a frenzy as they attempted to change the linen just hours before Kanye, 27, arrived at the event in Finsbury Park.

A source told the Daily Mirror newspaper: ''Kanye will only ever have a white dressing room, and this is usually included in his rider. But for some reason, there was black linen in his dressing room on the Finsbury Park site. This could not be allowed to happen. Organisers were told to get rid and replace it with the white stuff or Kanye wouldn't set a foot in there.

''Over the next few hours, festival staff were dispersed all over town to buy new crisp, white linen to replace it all. It was chaotic, but nobody wanted to upset Kanye. Especially as he'd stepped in to replace Drake at the last minute. There was pure panic for a while, but luckily, some were sourced just in time.''

The Grammy Award-winning rapper - who has a 12-month-old daughter North with his wife Kim Kardashian - is known for his outrageous requests after previously demanding that a white carpet backstage at the BBC be ironed before his arrival.

It is believed that Kanye insists on an all-white dressing room as it helps him to calm down and relax prior to his shows.

An insider close to the star said: ''Kanye is most comfortable when he's surrounded by white. It's just about having a serene place to relax before a big performance.''

They added: ''His tour management requested the switch from the black linen because it's their job to make the artist comfortable before he goes on stage.''
