Russell Watson has revealed that he almost pulled out of an I'm A Celebrity...Get Me Out of Here! trial because it reminded him of being in an MRI scanner.

The 54-year-old tenor - who has bravely battled two brain tumours in the past - explained that he began to feel panicked by the trial because of his association of MRI scanners and bad news.

The challenge in question saw Russell strapped into a rotating rack before being dunked into some horrific gunge.

Speaking about the Rancid Rotisserie challenge, Russell revealed that while he was nervous he eventually overcame his fears - which is exactly what he went into the I'm A Celebrity to achieve.

“I nearly pulled out of that… I got onto that rack and I’m petrified of MRI scans because I can associate them with bad news," Russell told the Mirror Online alongside other journalists.

"So I got onto the rack and I was lying on my back and there was a light shining on me and I thought ‘this feels like I’m about to go into the scanner’.

He added: "So I started to feel a bit panicky and… the guy said ‘I’m just going to strap you in now Russell' and as soon as he said that I thought ‘oh my God, oh my God’ and I was so close to saying ‘I can't do this’."

Russell was able to convince himself to remain calm and see the Bushtucker Trial through.

"And all of a sudden I just switched on and thought no, I can do this and I’m going to do this. That’s what I'm here for, I’m here to face my demons.

"I’m here to try and prove to myself that I can actually do this."

Russell has been very open about his brain tumour battle and has spoken about his ordeal with the campmates when they asked about it.

The dad of two was diagnosed with a brain tumour in 2006 and then received a second diagnosis one year later.

He has since been given the all clear, but recalls going through an endless cycle of MRI scans and hospital visits while battling the cancer.

While in the camp, he has also spoken about how his children had helped inspire him to remain positive.

"All I could think about was my children and slowly slowly whilst thinking about my children the clatter clatter of the MRI came back and I thought I’m going to beat this," he said in the camp.
