'Elton John saved me...'

Robbie has battled addiction in the past and recalled how music legend Sir Elton John - who overcame demons of his own - persuaded him to go to rehab.

He told 'The Jonathan Ross Show': "He really tried to help. In the early days when I was first getting sober, there was a week until I had to go to rehab and I had two vocals to do on my first album. He said, 'No you've got to go to rehab now" and I said, "I've got to go to rehab now' and this kept going back and forth at the door."

Elton took Robbie to his home in Windsor as the 'Rocketman' singer's husband David Furnish arranged for help for the 'Rock DJ' star.

Williams recalled: "I wake up but I haven't opened my eyes and there's a knock on my shoulder and I look and there's... Elton and David Furnish and a doctor and a psychiatrist and they are here to take me away."
