Justin Timberlake is writing songs for Madonna.

The Grammy award-winning star has revealed he is collaborating with Madonna on her new album, and was in a London studio with her yesterday (10.04.07).

Justin told Britain's The Sun newspaper: "I have been working on some new music. But it's not for myself - I'm writing for other people. I'm working on some stuff for Madonna."

The 'SexyBack' singer is in London preparing for the UK leg of his world tour.

Madonna - who has continuously re-invented herself throughout her career - is reportedly for her new LP to have an R 'n' B influence and has also enlisted the services of top producer Timbaland.

Timbaland has masterminded hits for Justin and Nelly Furtado and is desperate to help Britney Spears re-launch her career.

Madonna, 48, will headline this summer's Live Earth concert in London.
