While most of us have been stuffing our faces over Christmas and suffering from a post-food bloat, Charlotte has been oozing hotness.
Taking to Twitter on Boxing Day, 24-year-old Charlotte proudly showed off her killer body in the photo - and we don't blame her for wanting to show it off!
Wearing white pants and a grey vest rolled up to expose the lower half of her boobs, Charlotte told fans exactly how she'd gained such a jaw-dropping physique.
She wrote: "Morning workout #3MinBellyBlitz now back in my Pjs before long drive to london #HintOfCamelToe #Boobage#BeatTheBulge #Motivation."
Quite rightly, Charlotte's fans rushed to congratulate her on her super fit body.
One gushed: "Wow, you look stunning."
And another added: "WOW!!! You look amazing!! Can you tell me how you did this? Need to get back in shape following birth of my baby xx."
Charlotte is currently promoting her new workout DVD, Charlotte Crosby's 3 Minute Belly Blitz.
After relaxing her routine on Christmas Day, Charlotte was ready to hit the gym again on Boxing Day.
She told fans: "Right the indulgence stops here. GYM TIME."
The reality TV star has shed an amazing three stone since winning Celebrity Big Brother in 2013.
After leaving the house, Charlotte admitted her "weight was out of control".
Now Charlotte is barely recognisable... Girl, we salute your determination!
