Justin Timberlake is "seriously" considering being playing Sir Elton John in a biopic about his life.

The British singer has previously said he is very keen to have Justin portray him in the film - thought to be named 'Rocket Man' - and now the 'Social Network' star is giving thought to the huge part.

A source told E! News: "Justin is taking it very seriously. He's working with his people to figure out exactly how to respond."

Were he to sign up it would not be the first time Justin had played Elton - he previously portrayed his younger self in the video for song 'This Train Don't Stop Here Anymore'.

An official statement about the film is expected to made in the coming weeks, but Elton has revealed it will not be a straight-forward biopic.

He said: "It's going to be a surreal look at my life, and not just a factual look at my life, more in the manner of a 'Moulin Rouge!'

"I just don't want it to be a normal biopic because my life hasn't been like that."
