British songstress Jessie J has unveiled the music video for new single 'Silver Lining (Crazy 'Bout You)'.

The 'Who You Are' singer bares all in the video for the upbeat ballad which is taken from the soundtrack to Silver Linings Playbook starring Bradley Cooper and Oscar-nominated actress Jennifer Lawrence.

24-year-old Jessie - who sports long dark hair in the promo - is seen sitting on a chair while images from the romantic comedy are projected onto her naked body.

The singer also wears a sequinned minidress for final scenes in the video, showing off her new natural look.

Jessie took to her Twitter page to laugh off the nudity after posting a link to the video on the social networking site.

She exclaimed: "Naaakkkeeedneeessss lol (sic)."

Jessie is currently working on the follow-up album to her hugely successful debut release Who You Are, although there are currently no details as to when her second studio offering will hit shelves.

Much talked-about movie Silver Linings Playbook is released in cinemas from today, and tells the story of two strangers who form an unexpected bond.
