The Geordie Shore star was the best model for her own product as she wowed in a slinky pink bodycon dress that highlighted her toned figure.
Charlotte's on the promo trail for her latest offering, new DVD Charlotte's 3 Minute Bum Blitz, which promises to "blast off body fat and build a booty."
It follows her successful 3 Minute Belly Blitz, which focused on stomach muscles and is now a platinum-selling DVD.
And it looks like Bum Blitz will do the same as it went straight to number one in the fitness pre-order charts on its announce.
Charlotte explained on ITV's This Morning yesterday that she was inspired to create the bottom-focused workout after receiving nasty jibes online. "When I lost all of the weight, I would put workout photos on Instagram and videos doing different workouts and every comment was like 'well you're not really working out' or 'your bum looks so flat' which wasn't nice when I'd put so much hard work into it.
"I'd lost all this weight and I was getting more hate - it was like I can't do anything right."
