Others were quick to point out that Scarlett should be admired for her weight loss.

"Wow that's unbelievable look at you at the start and then look at the later on the later on one is outstanding you look so much better!", a fan said.

The star decided to take action and shed the pounds after finding out she was deemed obese after a trip to the doctor where she was told she was at a high risk of developing Type 2 Diabetes.

Saying the news was like "a rocket up her bum" the star cut out the "wrong things".

She dropped from a size 18 to a size 8 in six months.

Scarlett's fitness DVD shot up the top of the pre-order charts. It's officially out now.
