Kirin J Callinan has pleaded guilty to wilful and obscene exposure after lifting his kilt and flashing photographers on the Aria red carpet.
On 28 November, the 31-year-old Australian singer was egged on to lift his kilt. When he did, photographers and video operators recorded the moment outside Star Casino in Sydney.
Callinan has a reputation as a provocateur, and the Arias incident prompted backlash from some within the music industry.
In January, Brisbane rapper Sian Vandermuelen, who performs as Miss Blanks, confirmed she had sought Callinan’s removal from the lineup of the Laneway festival.
He was eventually dropped from the lineup, with Vandermuelen telling Triple J’s Hack program the alleged act “shouldn’t be tolerated”.
Callinan was expected to be sentenced at the New South Wales district court on Wednesday.
