Just look how beaut she is!
Josie was attending New Look's Winter Wishes Charity Ball, and teamed her revealing but classy AQ/AQ dress with a golden glow, killer smile, a black New Look clutch and black necklace from Complete Finishing Touch.
We have serious outfit envy, so we had a chat with Josie's stylist Hayley Sparkes to find out more.
Hayley, who is also a beauty presenter for This Morning, tells us: "Josie has really upped her style game since losing weight."
"Sometimes she is still a bit unsure of how to dress her new body, thanks to the weight transformation she's gone through," adds Hayley.
"So I've been helping her to up her style and celebrate her great figure."
We're impressed, Hayley! (Check out more of Hayley's work at www.hayleysparkes.co.uk.)
Josie, 28, had spent the day getting herself ready for the bash, held at London's Battersea Evolution, putting her hair in rollers and tweeting her progress.
The Big Brother star shed six stone earlier this year, going from a size 20 to a size 10, and has kept the weight off ever since.
But she recently admitted it's not always been easy, saying this summer: "Maintaining a body after weight loss is the biggest nightmare ever, far harder than losing the weight.
"But I never want to be big again - I used to cry every night."
