An artwork featuring Kylie Minogue's bottom has been pulled from the Royal Academy's summer show after the singer's lawyers complained, BBC News Online has learned.
The piece was to have been part of the academy's summer exhibition
The Academy was asked to withdraw Consumerism 2, by Dilek O'Keeffe, from the show and did so on Monday, the day the show opened to the public.
"The piece has been removed from the exhibition because our understanding is that the artist has breached copyright," a Royal Academy spokeswoman said.
Ms O'Keeffe told BBC News Online she was "dumbstruck".
"Having been selected from the several thousand submissions and to actually have got my work selected was mindblowing," she said.
Lawyers later sent a letter to the Royal Academy saying they believed the piece had breached copyright and that it was defamatory.
Ms O'Keeffe said she did not believe her work was harming the singer.
"Why a global star like Kylie Minogue should feel threatened is beyond me," she added.
Consumerism 2 features a cartoonish likeness of the singer, as well as a shot of her bottom and the word"talent".
The artwork also has the words "Na na na na na" - the chorus to her recent hit Can't Get You Out of My Head - written on her hand.
It formed a central part of the press view of the exhibition, held just last week.
The copyright dispute is over one of the images used in the artwork, which is also seen in the video to Minogue's hit song Spinning Around.
The Academy would not confirm whether the lawyers had taken exception to the cartoon of Minogue, or the bottom.
But it was not able to show work infringing copyright, added the spokeswoman.
A representative of Minogue would not make any comment when contacted by BBC News Online.
The summer exhibition, which includes work by Jake and Dinos Chapman, will run until 10 August.
Some 1,242 pieces were selected for the show, making it one of the largest open contemporary art exhibitions in the world.
