Taking to Instagram, Ruby shared footage of herself undergoing emergency surgery.

She wrote: 'To everyone asking about my new Pez dispenser scar on my neck, a couple of months ago I was told I needed an emergency surgery or I was risking becoming paralysed.

'I had herniated two discs doing stunts, and they were close to severing my spinal chord. I was in chronic pain and yet couldn't feel my arms.'
