Last night, Sophie returned to the house for the Geordie Shore: Birthday Battle and it is fair to say she almost looks like a different person altogether.
But Sophie insists her weight loss has been gradual and just seems dramatic as she has been out of the public eye for a while.
Speaking exclusively to MTV, Sophie explained: "For two-and-a-half years I haven't been seen, so now I do look a lot different to what I did.
"Now everyone's like, 'Woah, what the hell, Sophie's had this massive change', when in reality, I haven't."
Sophie has been in a relationship with bodybuilder and fitness model Joel Corry for four years and she credits the sportsman for indirectly helping her to shift so much weight and keep it off.
"He does competitions and stuff so I do sort of have his diet and I go to the gym with him and try and be as healthy as I can," she added.
Geordie Shore: Birthday Battle sees a host of familiar faces returning to the show to help either Charlotte Crosby or Gaz Beadle win a competition. The pair have been set the challenge of putting on the best club nights and they get to pick who is on their team.
Last night, Sophie was seen making her comeback and the moment left Charlotte cry tears of joy!
Sophie was originally axed from the MTV show in 2013 after being caught on camera making a racist comment, and she has since said it was the "biggest mistake" of her life.
Speaking to the Daily Star: "It was the biggest mistake of my life. It's the biggest regret and I am sorry. I had the best job in the world and to lose it was awful."
