MADONNA refuses to pay the London congestion charge because she does not want to reveal her address and phone number.

The music icon blasted Mayor Ken Livingstone's congestion charge after the Brit Awards.

Following her award for International Female Solo Artist, the American pop superstar said she was fined £100 every time she drove into the capital because she will not register her contact details with Transport for London.

The 47-year-old music icon lives in Marylebone with director husband Guy Ritchie and her two children.

"I'm p**sed off about the congestion charge. It's ridiculous. I live there and I gotta pay," a tipsy Madonna told reporters.

Registration number plates are scanned by cameras as cars enter, drive within or leave the charging zone and check it against a database.

Drivers are charged £8 if they pay by 10pm on the same day and are charged an additional £2 if they pay from 10pm to midnight.

Those who fail to pay the charge are fined £100, which rises to £150 if the fine is not paid within a month.

Madonna is eligible to get the 90 per cent residents' discount on the charge, which costs just £10 a year, but she refuses to hand over her contact details to transport authorities.

"I can't pay cos they want my phone number. Why would I give my phone number? I may get a pay-as-you-go phone so they can't know where I live, especially for that purpose," she said.

Today is the third anniversary of the controversial congestion charge.

From February 2007 the charge will extend west, covering Madonna and Guy's home neighbourhood.

Roger Evans AM, London Assembly Transport Committee chairman Roger Evans said the congestion charge still had teething problems.

"The impact on businesses is a major concern for many Londoners and it is questionable whether the Mayor's plans to extend the charge further into west London are justified," he said.

"Ken Livingstone has also upset many people by hiking the daily charge to £8, without any major evidence that congestion levels were rising in central London."

Despite the inconvenience of the congestion charge, Madonna said she was still enjoying life in London.

"I feel very comfortable here. When I get off the airplane and go through Heathrow, I feel like I've come home," she said.
