The Geordie Shore star, 25, grabbed her phone for the most envy-inducing selfie we've seen all Christmas.
Slipping into a neon pink bikini, Charlotte showed off her incredibly flat tummy, toned thighs and strong arms on Monday (28 December).
She told her Insta followers: "Be stronger, be fitter, be healthier and be happier."
Charlotte's been working her tiny tush off of late as she promotes her second fitness DVD, 3 Minute Bum Blitz, which promises to "blast off body fat and build a booty."
The star certainly looks like she's been doing her own workouts and told her Insta fans that the DVD is "the secret" to her fabulous figure.
Meanwhile Charlotte's also been taking the time to plan her outfit for New Year's Eve.
And with such a killer body, it's no surprise that the reality TV star is planning to show off a little bit.
Sharing a picture of one outfit option, from her own range with InTheStyle.com, Charlotte revealed a sexy hint of cleavage and quite a bit of toned thigh!
Looking good, Miss C.
Meanwhile Charlotte's... erm... mate Gaz Beadle has also been revealing quite a bit online.
Taking a snap of himself in the bathroom, Gaz forgot to put any pants on and ended up flashing his butt.
