No surprise that Jessie J has cancelled UK gigs

Not surprised that Jessie J has had to cancel her big gigs in Pontypridd and Alnwick Castle.

The 24-year-old chart star and Voice judge seemed out of sorts when she headlined a gig here at Warwick Castle last Friday.

During the show, she forgot the words to her biggest hit Price Tag, had to sit down for a while after pulling her neck and spent ages trying to re-attach an errant earring.

Right at the start of the show she said she was shattered after flying in from Switzerland, and hadn’t managed to do a soundcheck because she needed a nap.

(Although support band Lawson, who also flew in from Switzerland, seemed fresh as daisies).

And, of course, she made the grave error of inviting The Voice semi-finalist Becky Hill, who was in her team on the TV talent show, up onstage for a shambolic duet performance of Price Tag.

If you’re tempted to do it again, girl, please resist temptation. We’d all been waiting to hear you sing the hit we fell in love with, not some half-baked amateur hour.

Word is, however, that Jessie has now been diagnosed with cytomegalovirus (CMV), which can cause considerable fatigue.

In a message on her website Jessie said: “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 and to perform will make me worse.”

Jessie said she wanted to “personally apologise” to fans and was “just not well enough” to appear.

“Back to bed I go - so sorry,” she added.

Today her management issued a statement, which read: “On behalf of concert organisers KAL Music Limited, we regret to announce that due to the unexpected illness of Jessie J, we have been forced to postpone the concert at Alnwick Castle this Saturday 21st July  and reschedule to a later date.

“Following a visit to her doctor this morning, blood tests have revealed that Jessie is suffering from CMV, a virus which has caused her considerable fatigue. Doctors have advised that the exertion of performances this weekend would be likely to prolong the recovery period.

“The concert has now been rescheduled for 25th August with all existing tickets valid for this date. Any refunds will be made at point of purchase. Please contact your ticket provider directly for details. All refunded tickets will be re-issued and made available for purchase to the public at a later date.”
