Sir Elton John has reportedly signed a multi-million pound deal to pen an autobiography.

Rumours have been swirling over the past weeks that the rights to the veteran musician and AIDS activist’s memoir was being discreetly shopped to publishers.

It was confirmed today that the Rocket Man singer has signed a deal with publisher Pan Macmillan, reported to be worth as much as £6 million, for publication worldwide in 2019.

The deal specifies that the book will be the “first and the only official autobiography” of the music legend, spanning his decades of his extravagant public life.

It will cover his life from his early career and coming out to his battles with drugs and alcohol, his activism on gay rights and AIDS, and his later family life with partner David Furnish.

Sir Elton is collaborating with music critic Alexis Petridis on the “no holds barred account” of his life and work.

Sir Elton said: “I’m not prone to being a nostalgic person. I’m often accused of only looking forward to my next gig or creative project.

“It’s come as quite a surprise how cathartic I am finding the process of writing my memoirs.

“As I look back, I realise what a crazy life I have had the extreme privilege of living. I have grown up in a period of extraordinary change in our world – and have had the joyful honour of rubbing shoulders and working with so many of the people at the heart of these changes.

“My life has been one helluva rollercoaster ride and it’s still lumbering on. I hope readers will enjoy the ride too.”
