Britney Spears is desperate to meet Britain's Queen Elizabeth.

The 'Womanizer' singer – who is currently playing an eight-night residency at London's 02 arena – wants to take her two young sons, Sean and Jayden, to Buckingham Palace to have afternoon tea with the 83-year-old monarch.

A source said: 'Britney's schedule has been crazy from the minute she arrived in Britain. But no way does she want to leave without visiting the queen.

'She has told her aides she is desperate for her sons to rub shoulders with royalty. And she does not want to be disappointed.

'Britney loves everything the royal family stands for, so this would make a dream come true.'

This is not the first time Britney, 27, has shown her admiration for the royal family.

In 2002, she revealed the queen's grandson Prince William had cancelled a date they had arranged after talking over the internet.

Talking about their friendship, Britney said: "It was just, like, all blown out of proportion. We exchanged emails for a little bit and he was supposed to come and see me somewhere but it didn't work out.'
