Singer Jessie J said she was “lost for words” after a father-of-two died following a bottle attack at a star-studded party.
The Brit Award-winner performed at the function hosted by smartphone company BlackBerry before Phillip Sherriff (37) was fatally wounded.
He died in hospital yesterday morning after a four-day battle to save his life.
In a Twitter posting, the chart star wrote: “I am lost for words.
“All I can say is my thoughts, love and respects are with the family and children of the man who attended the blackberry gig last week who sadly lost his life this morning ... So sad.”
Mr Sherriff, a married telecommunications professional from Preston, Lancashire, was rushed to the Royal London Hospital in the early hours of Wednesday morning after suffering a neck injury at the Pulse nightclub.
Medics were later forced to operate on his skull to remove pressure from an injury to his brain.
“A post-mortem examination will be arranged in due course,” a Scotland Yard spokesman said.
Mr Sherriff had been invited to the BlackBerry function in Southwark, central London, along with a string of celebrities. These included rapper Wretch 32 and stars of The Only Way Is Essex.
Ashley Charles, a 25-year-old company director, was remanded in custody on Saturday, charged over the attack, which police are now investigating as murder.
Charles, of Nevanthon Road, Leicester, spoke only to confirm his name and date of birth when he appeared at Camberwell Green Magistrates' Court yesterday, accused of attempted murder.
The defendant was ordered to attend Inner London Crown Court on April 20 and an application for bail was refused.
