Rebel has gone from strength to strength in her quest to be her healthiest self and has shared her inspirational journey with fans.
During a recent virtual appearance on The Drew Barrymore Show Rebel lifted the lid on her decision to undergo a health transformation and explained: "So the last few years I’ve been theming my years. So like, the 'year of fun', last year I had the 'year of love' and then this year, I was like, it's going to be the 'year of heath'."

Rebel said turning 40 in March was an eye-opener for her and made her realise she had never really focused on her health.
"I was going all around the world, jet-setting everywhere and eating a ton of sugar," Rebel admitted. "That was my vice. I have a very sweet tooth. I love desserts.
"And I've tried, like so many women out there, I've tried fads and diets and things before and I’m like, I need to do a really holistic approach to this, this time."
The views are incredible
She said stress was a major factor in her overeating and she realised she needed to value herself more and treat her body better.
Rebel changed her eating habits and introduced more exercise into her routine and she's never felt better.
"So I've lost, I think it’s like 40lbs this year so far and I want to lose a few more," she added before the audience erupted with applause.
