The 26-year-old stars as pop star Ashley O, who has a strong desire to leave behind bubblegum pop for edgier material, in the season five episode "Rachel, Jack and Ashley Too". And, in an interview with Digital Spy, Brooker highlighted the parallels between the story of a comatose pop star being exploited by her record label and the "Wrecking Ball" hitmaker's career.
"I wasn't specifically thinking of one individual person (when writing)," the show's creator said. "But you know about pop stars, and the problems they have, and the troubles they go through."
"Ashley O has this dodgy doctor feeding her pills and, actually, in the real world that's not that far-fetched - as we know from other pop stars."
"Black Mirror" executive producer Annabel Jones went on to share that the "Mother's Daughter" singer - who started out her career as Disney Channel character Hannah Montana before veering away from the polished image - was more than happy to exploit the similarities with her own artistic journey.
"As you can imagine, there were quite a few things in the script that she identified with," she elaborated. "She's got a very sarcastic sense of humour. She's very acerbic, she's very funny, and she delights in subverting things. Her whole career has been about (being) the Disney pop star who tries to carve out her own identity and as a result has faced a lot of opposition - from her label, and her fans in some respects."
"She's been on that journey, so she found it hilarious. She said, 'I'm going to have so much fun with this!' "
Season five of "Black Mirror" drops on Netflix on Wednesday, June 05
