Christina too sick to tour

Christina Aguilera won't be entertaining fans in the U.K. anytime soon.

The 19-year-old pop star is suffering from exhaustion and has cancelled her UK tour, ITN Online reports.

Christina is said to have an ear infection and a "serious" flu and was told to avoid flying for more than three hours at a time. She is relaxing and recovering in Miami with her family.

Christina also cancelled an appearance at the World Music Awards in Monaco.

"I'd like to reassure my fans that my illness is not too serious, but it's important for me to rest for a while and look after my health," she said.

"I am disappointed that I've had to cancel various things, and I'm looking forward to getting back on my feet and visiting Europe." A computer virus has attacked the schedules of two U.K. pop stars.

The "I Love You" virus that swept computers through an email last week has affected the schedules of both Robbie Williams and Geri Halliwell, ITN Online reports.

The virus hit the two stars' record companies and caused chaos with their media itineraries.
