Cox went on to address her previous use of cosmetic procedures, explaining: “I was trying to keep up with getting older and trying to chase that. It's something you can't keep up with. The more you relax with it and the less you try...

“Sometimes you find yourself trying and then you look at a picture of yourself and you go ‘oh god, I look horrible.’”

The 52-year-old continued: “I have done things that I regret and luckily there are things that dissolve and go away. So that's good because it's not always been my best look.

“Now I have a new motto; let it be.”

Despite the pressures that come with working in the industry, however, Cox added that she wouldn't change a thing about becoming famous.

“I don't feel burdened by it, but people can be mean on social media.”

Grylls, moved by Cox’s honesty, praised her for opening up about the issues so many women face on a daily basis.

“The natural you is amazing,” he added. “And there’s light in your eyes.”
