Taylor Momsen has stripped down for her new music video.

The former 'Gossip Girl' star turned rebellious rocker - who is well known for her desire to shock and her love of heavy eye makeup and extremely revealing clothing - is baring all and appears completely naked in her new spoken word video for her band's new song 'Under the Water'.

The 19-year-old 'The Pretty Reckless' singer looks super skinny in the black and white footage in a newly released clip called 'The Words' directed by Tim Mattia that begins by focusing on her different body parts and ends by showing her fully naked.

The artistic footage of the starlet - who found fame at the age of seven after starring alongside Jim Carey as Cindy Lou Who in 'How the Grinch Stole Christmas' - includes audio of Taylor narrating the lyrics of the band's controversial new track.

The song includes the lines: ''Broken lines, across my mirror. Show my face, all red and bruised. And though I screamed and I screamed, well no one came running. No I wasn't saved.''

The blonde singer - who previously admitted she is ''completely neurotic'' - posted the clip on twitter earlier today (14.10.12) and asked her 600,000 followers to share it.
