Chris Martin has recorded a hip-hop track with Jay-Z - but his rapping attempts have failed to make the cut.
The 'Coldplay' frontman - famous for penning melodic hits such as 'Yellow' and 'Clocks' - collaborated with the hip-hop star on a yet unnamed tune for Jay-Z's new album 'Kingdom Come'.
Chris then decided to try his hand at mc-ing, but his efforts will not be included on the LP.
A source told Britain's Daily Star newspaper: "Jay taught him a verse and he was recorded doing about a minute of it.
"It's not for Jay's album, it's just a bit of fun. Chris loved it and had a laugh holding the microphone like a rapper and grabbing his crotch while he was rhyming."
Despite not making the album, Chris's rap has been a hit with the New York club scene.
The source added: "It's now on a mix-tape doing the rounds in New York."
Chris - who is married to actress Gwyneth Paltrow - has previously collaborated with Kanye West and the 'Streets' rapper Mike Skinner.
