Ill Jessie J cancels concert

British pop star Jessie J has scrapped a gig in Wales after contracting a viral infection.

The Domino hitmaker was set to take to the stage at the Ponty's Big Weekend event in Pontypridd on Friday night (20Jul12) but has fallen ill.

The star took to Twitter.com to apologise to fans, and admitted the bug has left her too tired to perform.

In a series of posts, she writes, "I want to personally apologise to all my fans who would be going to my show tonight (Pontys Big.W). I have been diagnosed with a viral infection recently that has caused me to be extremely fatigued.

"I was hoping to be better but I have been to see my doctor this morning after not feeling great who has advised me I am still in need of rest & to perform will make me worse. I hope you can all understand that I wish I could be there. But I'm just not well enough. Back to bed I go. So sorry."
