Paris Hilton's week has failed to get any better after she appeared in court to admit cocaine possession - she has now been refused entry to Japan.

The socialite arrived at Nartia International Airport a day after the conviction and was held by immigration officials.

The 29-year-old was reportedly interviewed for six hours, with authorities planning more questions on Wednesday.

There is also speculation she was forced to check into a budget airport hotel, while her sister Nicky went onto their five-star resort.

The pair were due in the country to promote their fashion and fragrance lines. The press conference scheduled for Wednesday has been cancelled.

Hilton was fined £1200 on Monday, ordered to do 200 hours of community service and given a one-year suspended sentence after admitting to carrying drugs in Las Vegas.
