The singer’s mother Marie broke the news in an Instagram post on Sunday, announcing that her daughter had died that morning.

Alongside a black and white photo of the star, she wrote: ‘It’s with deep heartbreak that today I’m sharing the news that my beautiful daughter Sarah has sadly passed away.

‘Many of you will know of Sarah’s battle with cancer and that she fought so strongly from her diagnosis until her last day. She slipped away peacefully this morning. ‘

Marie continued: ‘I’d like to thank everyone for their kind support over the past year. It meant the world to Sarah and it gave her great strength and comfort to know she was loved.

‘I know she won’t want to be remembered for her fight against this terrible disease – she was a bright shining star and I hope that’s how she can be remembered instead.
