What Britney Wants At London Hotel

Everyone in London is excited about Britney Spears' arrival next month for an eight-show stay at the O2 arena.

The Circus, Spears' first arena tour in five years, began March 3 in New Orleans and wound up its U.S. and Canada dates April 29 in Chicago. The star will take a short break before taking the tour to London.

According to Billboard magazine, the tour is the second most profitable, grossing $4,062,953. Elton John's run at Caesars Palace in Las Vegas is number one.

And when the pop tart does check in to the Dorchester Hotel, a favorite of Elizabeth Taylor's, she's voiced a few requests for things she'd like upon check-in.

Here are some of the demands from Spears' rider, courtesy of an employee on the hotel circuit.

• A room that has "never" been smoked in at all.
• Humidifiers in all areas.
• A selection of the latest magazines.
• A fresh selection of flowers that she will then arrange herself.
• DVDs of her favorite Marilyn Monroe movies.
• Books. Ideally, topical chick lit novels.
• Lighting must be 100 watt bulbs - no low lighting.
• Running routes for nearby Hyde Park. Also, horse-riding opportunities.
• A list of different routes to the venue from the hotel to keep the paparazzi at bay.

The singer will be bringing her own pillow supply. It's nothing to do with the hotel, her staff says, it just a comfort thing.

Also, security will sleep outside her room.

Spears will check in under various names. So far one been Sugar Kane, a reference to favorite Monroe movie "Some Like it Hot."

She has also requested tickets for various West End shows, including the Michael Jackson musical "Thriller," but it's unclear if the seats are for her or the dancers.

Also, she's more than keen to take in a "private " visit to Kensington Palace - the former home of one of her icons, the late Princess Diana. My source reveals, "She travels with a picture of Diana and Marilyn at all times and thinks they are great, powerful women."

Finally, the singer won't relocate for her subsequent shows in Manchester. Spears will still be staying at the Dorchester and travel by plane to the concerts.
