Elton John and Lady Gaga have recorded a duet exclusively for the ‘Gnomeo and Juliet’ film soundtrack called ‘Hello, Hello’ which will be available for purchase on February 8, 2011.

 The song was recorded back in October, with Lady Gaga documenting the occasion by tweeting: "Eltoneo + Guliet! Finishing our duet Hello, Hello in studio. Sounding so amazing, some last finishing touches and off to the movies!"

The song will reportedly make its appearance in the film when the lead characters Gnomeo and Juliet meet for the first time. Including the collaboration, the soundtrack features 14 songs, of which Elton sings on seven. There will also be a new version of Elton’s 1972 hit ‘Crocodile Rock’ recorded by Nelly Furtado.
