Shia LaBeouf has thrilled fans by stripping down in a new music video.

The "Transformers" star has given Icelandic band Sigur Ros a boost by appearing naked in their arty video for instrumental Fjogur Piano, and seductively embracing blonde actress Denna Thomsen.

The erotic, seven-minute promo, designed to portray "a man and woman locked in a never-ending cycle of addiction and desire," was directed by filmmaker Alma Har’el.

According to the Wall Street Journal, the actor reportedly approached Har'el about working on the production after watching her film Bombay Beach, which won the documentary feature prize at New York's Tribeca Film Festival last year.

This isn't the first time LaBeouf has dabbled in the music industry - he recently financed and filmed a video to accompany the teaser trailer for Marilyn Manson's new album Born Villain.
