And for those who have been wondering how she shed the pounds so quickly, the wait is over, as she's revealing her exercise secrets in her new fitness DVD, Scarlett's SuperSlim Me Plan.
The DVD claims that it's possible to lose more than half a stone in the first week of working out Scarlett-style. Together with her trainer Lee, the 26 year old will show viewers how to complete full body workouts, as well as shorter exercises of 5-7 minutes for when you're short on time - and there's even advice on nutrition and diet to help you speed up your fat loss.
The cover shows Scarlett in a red bikini both before and after her transformation from a size 18 to a size 8, showing off the dramatic results that it's possible to achieve on the plan.
Scarlett officially announced the DVD back in October, sharing a video message of herself in workout gear on her Instagram account and exclaiming: 'So loads of you have been asking us how I've lost the weight, and now, you'll all find out, because my DVD is out for pre-order today!'
The reality star, who had recently celebrated her birthday, then followed up with a picture of the temporary artwork for the DVD, adding: 'When you can eat 2 types of birthday cake and not feel guilty because you know you can just smash the DVD 💪🏽 lovelies it's out for pre order on amazon now, the fact that I'm a bloody professional couch potato & did it, I am 10000% positive you lovely lot can ❤️💪🏽 #motivation'.
Scarlett has been vocal about her workout regime in recent months, and credits much of her success to gym-mad boyfriend Luke Crodden.
'My boyfriend is super-fit so it's quite good having him on side because he's quite motivated. I've got no excuse now!' she told new! magazine earlier this year.
'I've just started exercising quite a bit actually. I'd say I do HIT [High Intensity Training] about three times a week.'
Scarlett's fans seem very excited to find out exactly what moves she's been doing to achieve her incredible results, with one commenting: 'Pre-ordered!! Can't wait!! You've inspired me ... I am struggling to believe I can get the body I want so hopefully this will help!!'
Another added: 'Cannot wait to get this and lose my baby weight!!!!! Well done @scarlett_moffatt you look fabulous even though I never thought there was a problem before!'
