Thom Yorke is working on a rap album.

The singer - who recently released eighth album 'The King of Limbs' with his band Radiohead - may collaborate on an entire album with rapper MF Doom after it was confirmed they have joined forces on a number of tracks together.

MF Doom told 3D World magazine: "We're working on some duets It's just preliminary sh*t but we will probably end up doing a whole record together.

"We've got some ill a*s ideas."

This isn't the first time the unlikely duo have collaborated, as Thom previously appeared on a remix of the rapper's 'Gazzillion Ear' in 2009.

Meanwhile, Thom has also revealed this week he will be collaborating with folktronica star Four Tet and dubstep hitmaker Burial for a new double A-side single entitled 'Ego' and 'Mirrors'.

The release will be limited to just 300 copies and will be put out through Four Tet's own label, Text.

Radiohead recently surprised fans by 'The King of Limbs', as it wasn't known they were in the studio or had even started writing songs to follow up 2007 album 'In Rainbows'.
