Jessie J 'Party in the USA' demo unveiled online - listen

Jessie J's original version of 'Party in the USA' has been uploaded online.

A clip of the track - later recorded and made famous by Miley Cyrus - was uploaded to SoundCloud by songwriter and producer Claude Kelly.



"In the studio with Jessie J reminiscing about how it ALL got started. Pea, Moonhead and the incredible Coconut Man. this is the first song we ever did. i guess we did ok, right?" Claude wrote underneath the snippet.

"s/o to @mileyCyrus for giving @jessieJ her first HIT record record. and starting off a amazing journey for us all," he tweeted.

However, Jessie J's version slightly differs from Cyrus's final edit. Instead of the chorus including the lyrics "party in the USA", it goes: "I think I'm going to like it in the USA."

Jessie J is currently working on the follow-up to her 2011 debut album Who You Are, which spawned the hits 'Price Tag', 'Do It Like a Dude' and 'Domino'.
