Charly Clive is an English actress, known for her role as Marnie in the television series Pure. In 2015, aged 20, after being diagnosed with a brain tumor, she wrote about her experience in a sellout comedy show called Britney, which was named after her brain tumor, which in turn was named after singer Britney Spears: "I needed it to be iconic, and there is nobody more iconic than Britney. If I was going to get a tumor, then she'd have to be a little bit fabulous, and so Britney was the one".

She was nominated as one of the Screen Stars of Tomorrow in 2018. A television sitcom adaptation of Britney debuted on BBC Three in November 2021 to critical acclaim.
