Justin Timberlake is to make his debut as a rapper on P Diddy's new album. 

P Diddy's first record as part of his new Diddy-Dirty Money band, 'Last Train To Paris', features a track with a rap by Timberlake. 

"I can’t wait for people to hear this song," P Diddy gushed. "It’s called 'Shades' and it’s going to blow you away. I’m the main vocalist on it and JT does the backing vocals and then unleashes a rap. It’s the first time he’s ever rapped on a song and you’re going to love it. It’s a very sexy song. It’s the sexiest song on the album. Everyone’s trying to sound like our labelmates the Black Eyed Peas. Whenever you follow people and try to copy their blueprint, that’s when you fail. We have our own blueprint, our own style. We respect everyone else’s music but we’ve got something else to bring to the table. We’re refreshing and innovative."
