Shia LaBeouf has bared all for the first time, in a music video for Icelandic indie band Sigur Rós.
The Transformers and Indiana Jones actor gives a brave performance in the arty clip for the song 'Fjögur Píanó', in which he and actress Denna Thomsen act out an odd, heartfelt relationship.
They swap clothes and perform an interpretive ballet together. However, things get a little strange - and violent - as the song continues.
This is another attempt by Shia to prove his worth as an 'edgy' actor, after he directed the ultra-violent, serial-killer short film Maniac with rapper Kid Cudi.
Warning: this video contains full-frontal male and female nudity and disturbing violence.
Shia's career is getting more interesting by the day!
