Kylie Minogue and Coldplay have teamed up for a special duet.

The singer, 40, and the band – led by frontman Chris Martin, 31 - recorded the new song Lhuna last month.

‘This is the duet of the year – you don’t get bigger than Kylie and Coldplay,’ a source tells the News Of The World.

‘It’s taken a number of weeks but they finally finished the track last week.

‘It’s something they’re very proud of because it’s being released with the soul aim of raising money for a cause that is very close to their hearts.’

Lhuna is available for download exclusively on Red Wire.
