Fans of The Voice coach Jessie J may recall that back in April, she played at a gig to launch a new BlackBerry product, but the event – which was attended by dozens of celebrities – ended in tragedy when fan Phillip Sherriff died after being stabbed in the neck with a broken bottle.

Medics rushed to the venue in Southwark, south London, and began lifesaving emergency treatment on 37 year old Mr Sheriff, but he sadly passed away just days later.

Meanwhile, 25 year old company director Ashley Charles was arrested in connection with the incident, and after Mr Sheriff died, he was charged with murder.

At the time, Charles denied the charges but was refused bail and remanded in custody until the hearing yesterday, when he appeared at the Old Bailey via video link from Belmarsh Prison to enter his not guilty plea. He was again remanded in custody until his trial on October 29…

In response to the news, Jessie J, who’s currently touring Europe, tweeted, “LIVE for every single moment. LAUGH until your face hurts.

“LOVE someone so much you feel FREE. Remember LIFE is so precious. And it’s YOURS.”

And at the time of the incident, before Mr Sherriff died, she took to Twitter to say, “My thoughts are with the person who was seriously injured last night at the blackberry bbm party.

“So sad. I really hope they are ok.”
