A British YouTuber and musician accused of violently raping a fan after a gig in Perth was an entitled semi-celebrity who cared little for his alleged victim, a jury has heard.

British rapper Yung Filly is expected to testify at a rape trial where he is accused of sexually assaulting a fan during his Australian tour almost two years ago.

Andres Felipe Valencia Barrientos, better known as Yung Filly, is accused of biting, slapping, strangling and raping a 20-year-old fan after a gig at a Hillarys nightclub.
