Everybody wants to be a rapper. JUSTIN TIMBERLAKE is busy writing songs for MADONNA.

“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,” J.T says.

Justin headed into a West London studio yesterday with Madge.

The singer is in the U.K for a few weeks as he prepares to kick off the UK leg of his current world tour.

Madonna’s album will have a real hip-hop feel.
