Rihanna is being sued by a second photographer who claims images in her "S+M" video were stolen his work.
The Barbadian singer was first handed a lawsuit over the raunchy video by fashion photographer David LaChappelle who alleges "the music video is directly derived from, and substantially similar to the LaChapelle works."
Now a second photographer, Paris-based Philipp Paulus, has joined him with a second copyright infringement suit, saying his images were recreated without permission for "S+M's" bondage-themed video.
He singles out a particular shot of his where a model in a billowy gown is trapped against a wall by a sheet of plastic, surrounded by large X symbols made from black tape, which is very similar to how Rihanna is presented in part of her video.
Philipp told Radaronline.com: "Why a worldwide celebrity is not able to afford a creative director, who creates individual concepts and stagings, is incomprehensible to me.
"To create new things within the creative cosmos, you can only expect this to come from a real genius.
"However, in this case there is no real genius who created their own work; instead they stole ideas from a creative talent."
Neither Rihanna nor her record company, Universal Music, have made comment on the video, directed by Melina Matsoukas.
