The blonde bombshell looked stunning as she debuted her weight loss on ITV's new lunchtime show Let's Do Lunch With Gino And Mel.
Josie was prompted to lose weight after coming out of the Big Brother house in 2010. She managed to slim down from 16st 7lb to 13st 7lbs but piled the pounds back on soon after.
Talking about losing weight, Josie said: 'I came out of the Big Brother house looking like Ten Ton Tessie. I put on a good two stone in the house. I didn't stop eating in there. I love my food.
'Obviously I wanted to lose weight as I'd turned into a bit of a heifer.
'Now I just feel really fit and healthy.'
Josie underwent a lifestyle overhaul in order to shed the weight she had gained partying and filling up on fast food.
‘Before I lost weight I was nearly size 20 and my only exercise was partying. I've tried all the diets - I did the Cambridge Diet and lasted from the meeting until I got home!
'They gave me all the bits and pieces but I ate a week's worth of food on the spot, then stopped for a kebab.'
The new Josie now doesn't drink so often and chooses to opt for healthier options.
Well, congrats on the weight loss Josie - we think you look fabulous!
