It’s also likely fairly obvious that Lee doesn’t have a weak stomach. In a recent interview with the Daily Mail’s Femail, she revealed that there is one thing that does gross her out.

"I often get asked if there is anything that is just too vulgar for me to do and my answer is always no,' she told Femail. "However, there are certain things that do gross me out like sick and I also have a thing for fungus on toes, I mean that is something I literally can't bear. My husband is a dermatologist and he removes toenails — I could never do that, it is like barbaric."

"At the end of the day it is my job I am showcasing and I would never want to embarrass my patients by squirming at their skin condition or making them feel uncomfortable. My reputation is at stake."
