Jessie J hopes to continue tour despite ilness
Jessie J is looking to continue her Heartbeat tour in Manchester tonight (21st October), despite being poorly.
The Price Tag star, who is due to perform at Manchester Apollo, revealed she was feeling under the weather in a post on Twitter.
She wrote: "No shows are cancelled #heartbeats I'm just not very well. The weather change always gets me. I'm resting and hope to be ok for tonight. X."
Jessie kicked off her UK tour in Birmingham earlier this week and the chart-topper revealed that fans should expect the unexpected when she releases her second album, which might have a folk feel about it.
"I get up and I wear different clothes everyday and music should be a reflection of that, and a reflection of what it is today," she said.
