The reality TV star, 24, is currently promoting her keep fit DVD and is keen to flaunt her new body - and who can blame her!?
Taking to Twitter on Saturday (3 January), Charlotte posted before and after pictures of her weight loss journey.
The first is when she weighed 11 stone not long after winning Celebrity Big Brother in September 2013.
The second is now - after losing two and a half stone.
Alongside the snap, Charlotte told fans: "Motivational before and after!!! YOU CAN get results! [...] #MakeANewStart #NewYearNewYou#HardWord #Determination#ThisPhotoKeepsMeMotivated sorry for the extreme paleness and lack of makeup LOL."
It's clear Charlotte is proud of how far she's come, and her fans seemed just as impressed.
One said she looked "amazing", while another said "look at her transformation! Wow!"
Although one fan disagreed, saying: "Preferred her before, looks poorly, good on her tho but like my women with curves."
