Actress/singer Taylor Momsen has shocked fans by appearing completely naked in The Pretty Reckless' new video.

The former Gossip Girl star is heard reading lines from the song Under the Water as the camera focuses on a series of close-ups.

Lyrics include, "Don't let the water drag you down/ Don't let me drown in the waves... Alone I pray for calmer seas/ And when I wake from this dream with chains all around me/ I've never been free."

As the verse finishes, Momsen is filmed standing nude, with soft lighting the only thing stopping viewers from seeing the star's genitals.
