Britney Spears' hotel demands for her upcoming London residency have reportedly been leaked to the media.

According to CBS News, an employee at the Dorchester hotel where the singer will stay during her eight-date run at the O2 arena has handed over details of her requests.

Among the star's reported wishes are a room that has never been smoked in, humidifiers in all areas, 100 watt bulb lighting and a selection of fresh flowers that she will arrange herself.

Digitalspy reports that she has also allegedly asked for a variety of the latest magazines, DVDs featuring Marilyn Monroe and a selection of topical, chick-lit books.

Running routes through nearby Hyde Park and horse riding opportunities are also thought to have been requested, along with a selection of different routes from the hotel to the arena in order to keep the paparazzi away.

The employee added that Spears will be bringing her own pillows for comfort, security will sleep outside her hotel door and she wants tickets for various West End shows and a private visit to Kensington Palace.

Spears is scheduled to arrive in London next month ahead of her opening show on 3 June.
