Cyrus starred in "Rachel, Jack and Ashley Too," an episode of the Netflix science fiction series "Black Mirror", which she filmed in South Africa in November 2018. It was released on Netflix on June 5, 2019. In the episode, she played fictional pop star Ashley O and provided the voice for her AI doll extension, Ashley Too. The music video for the song "On a Roll" from the episode was released on June 13; the song itself and the B-side "Right Where I Belong" were released to digital platforms the next day. On June 27, it was revealed that Cyrus had collaborated with Ariana Grande and Lana Del Rey on "Don't Call Me Angel", the lead single of the soundtrack to the 2019 film "Charlie's Angels." It was released on September 13, 2019. In August 2019, Cyrus released "Slide Away", her first song since announcing her separation from then-husband Hemsworth. The song hinted at their breakup and contained lyrics such as "Move on, we're not 17, I'm not who I used to be". A music video was released in September 2019 that contained further references, including a ten of hearts playing card at the bottom of a pool to represent the end of her decade-long relationship with Hemsworth.
