Spears' bodyguards are never far behind

But a spokeswoman for Top of the Pops said she made no big demands - in contrast with the reported requests of singer Jennifer Lopez.

Lopez allegedly requested about 10 dressing rooms for herself and her entourage for an appearance at last year's Top of the Pops music awards.

"Britney has made no outlandish demands and she only has an entourage of about 20 - half of what J-Lo had," the spokeswoman said.

"Of course she has a couple of minders but other than that she is just here with her dancers and her band."

Thrilled

Before going to the chart show's studios in west London, Spears went for a walk around Hyde Park with her bodyguards.

She then went shopping at the Knightsbridge store Harvey Nichols.

Despite her huge fame, fellow shoppers and sales staff reportedly failed to recognise her as she spent half an hour looking at clothes and jewellery.

On Friday, Spears is scheduled to meet Skinner who said on Thursday that he was thrilled at the prospect of meeting her.

"She is the hottest pop star in the world at the moment, and in more ways than one," he said in a statement.

"The big question is will she put her career on the line and do a song with me at the end of the show."

His interview with Spears will be shown later this month.
