British soul singer Joss Stone has celebrated Christmas early by recording a festive duet with Elton John.

The odd couple, who are close pals, recorded CALLING IT CHRISTMAS for Elton's upcoming holiday album ELTON JOHN'S CHRISTMAS PARTY.

The album features the rocker's favourite festive tunes from stars like THE Pretenders, Bruce Springsteen and Otis Redding.

The album will be sold exclusively through coffee shop chain Starbucks and a portion of the profits from every sale will go to the Elton John Aids Foundation.

Elton is no stranger to Christmas hits - his STEP INTO CHRISTMAS classic has been a perennial festive favourite for years.
