Posing next to a cardboard cutout of herself at her heaviest, the former Big Brother star was all smiles at today's photocall in London.
And no wonder!
Josie looks incredible! The starlet is hoping she can use her experience of weight loss to help others through her website, which provides training tips, recipes and other incentives to lose weight in a healthy way.
The reality star recently told Reveal how happy she was with her body - and how it's improved her love life!
"Before I lost the weight, I was too scared to even walk around my local pool without a towel wrapped around me. But now I'm happy to walk around in my swimming stuff, and I can finally be naked in front of my man too!"
