Essex singer Jessie J has been admitted to hospital

Singer Jessie J, who recently scored a top 30 hit with her debut track Do It Like A Dude, has been admitted to hospital with a "severe virus".

The Essex newcomer has been forced to postpone her biggest headline gig to date at London's Scala (7 December).

Writing to her followers on Twitter, J thanked fans for their support saying: "I am very weak and in hospital resting."

Her record company has asked fans to hold on to their tickets.

A scheduled show set to take place at Brighton's Coalition on 11 December currently remains unaffected.

This week the 22-year-old singer was included on the BBC's Sound Of 2011 long-list, tipping next year's most exciting new musical talent.
