Michael Jackson died tonight following a heart attack at his Los Angeles home. The Los Angeles Times reported Michael was not breathing after emergency medics were called to his home to perform ‘cardiopulmonary resusciation’ – when this failed to revive the star, he was rushed to the UCLA Medical Centre hospital, where both the LA Times and celebrity website TMZ were the first news outlets to report the music legend was pronounced dead.

Michael was due to start a series of comeback concerts in London this summer, and had been rehearsing his show in Los Angeles for the last two months.

The LA Times said on its website: “Pop star Michael Jackson was pronounced dead by doctors this afternoon after arriving at a hospital in a deep coma, city and law enforcement sources told The Times.”

While some major news sources – including Britain’s The Times and the Guardian were still awaiting confirmation of the news – many gossip websites, blogs and social networking sites were already reporting that Michael Jackson had indeed died, with tribute groups springing up on Facebook and Twitter.

The news has left millions shocked as music fans across the world mourn the loss of one of the most influential, famed and, at times, controversial stars of our time.  Michael sold more than 750m albums worldwide and won 13 Grammy awards, and is an individual whose worldwide popularity and fame broke racial barriers and announced the arrival of a new chapter in pop music and performance.

More news is expected to follow, and t5m’s thoughts and sympathies are with Michael Jackson’s friends and family.

It truly is the end of an era.
