Eminem is one of the collaborators on Lil' Wayne's long-awaited new album 'Rebirth', it's been revealed.

The Grammy-award winning rapper features on a track entitled 'Drop The World'.

The full tracklisting for 'Rebirth' appeared online on Monday but as yet only Eminem's collaboration has been confirmed.

Lenny Kravitiz and Fall Out Boy have previously been linked to the album.

'Rebirth' is due to be released on December 21 – eight months after it was originally scheduled to hit shops.

The rap-rock record is one of two new albums expected from Lil' Wayne before he is sentenced in February for attempted gun possession.

The rapper, who pleaded guilty during a court appearance in New York last month, is also preparing to release 'Tha Carter IV'.

It will mark the follow-up to 2008's 'Tha Carter III', which sold over 1 million copies in its first week of release.
