Beyonce Knowles requested a 'wind machine' at a London nightclub.

A source said: "Beyonce arrived at about midnight with a massive entourage.

"On her table, alongside huge treasure chest cocktails, she had a big industrial fan which remained just inches from her face to keep her hair blowing everywhere - just like it does in her 'Crazy in Love' video."

This is not the first time the 'If I Were A Boy' hitmaker's extravagance has drawn attention this week.

While performing in Liverpool, the singer booked a separate hotel room to house her 21 pieces of luggage.

A source at the city's Malmaison hotel - where the star took a ￡170-a-night room for her luggage - said: "She had seven suitcases, three hand-luggage bags and two boxes, all for her mammoth concert. In the cases there were, apparently, 14 dresses, lots of shoes, make-up and 25 wigs."

It took four helpers to carry her luggage up the stairs to the room, which was situated close to the Liverpool Echo Arena, where she performed twice this week.
