In a video posted to her YouTube channel on 18 July, months after revealing that she had been diagnosed with a brain tumour, Isabella gave an update on her condition.
She filmed herself undergoing an MRI scan in the video, entitled ‘Goodbye hospital’.
She revealed she was cancer-free in a video she recorded while driving and shared the results of her scans.

Since then, Isabella has kept a diary of her battle with cancer on YouTube.
Last month, she posted a video of herself and her family celebrating her last chemotherapy session in hospital.
The video shows her walking down the hospital corridor while her family and friends throw confetti at her.
