Robbie Williams has been offered £1.5 million to play a half-hour concert - but is planning to turn it down.
The 'Angels' singer has been offered £50,000 a minute to headline a music festival in Norway - but he is unsure whether to accept as he has vowed to give up touring.
A friend of the star said: "It would probably be the easiest money he'll make in his life but it's touch and go whether he'll say yes. We'll have to wait and see."
The 34-year-old recently posted a message on his personal blog saying he has no wish to return to live shows because his last tour "nearly killed" him.
He wrote: "The more time I'm spending away from public life, the more I like it."
Despite the poor reception to his last album, 2006's 'Rudebox' and his threats to withhold his next album due to a dispute with his record company EMI, Robbie did confirm he will be releasing new material.
He added: "There definitely won't be a tour anytime soon.
"I might put the B-sides to the next album out first online. Then put an album out in 2009 which means you won't be seeing a lot of me on stage."
