Scarlett also admitted taking part in the show was even more challenging than she expected it to be after watching it from the comfort of her sofa.
“I think it’s tougher because you can’t smell the smells and see all the flies. It’s actually rank,” the star explained.
Scarlett is currently taking part in The National Lottery’s 25th birthday celebrations and marked the occasion by helping them break the world record for the largest ever cream tea party back in October.
