The former TOWIE star decided she was her own best advert, slipping into a cute paisley print bikini that is available at her Lucy's Boutique.
Well, why not!
And if you fancy getting your hands on Lucy's exact bikini, it's the 'Kourtney Bikini', available now for £32.99.
Lucy snapped her selfie in the bathroom mirror and was, as you'd expect, inundated with many compliments by admiring followers on Instagram.
It's no surprise Lucy's got a hot bod considering she's the owner of a fitness and nutrition brand called Results With Lucy, which offers online tutorials and advice, and runs a series of booty camps.
She's also just launched a supplement called Mecktone.
This week, the brunette was at the Trafford Centre in Manchester, where she led a live fitness class for shoppers and officially launche Mecktone at Superdrug.
