The former TOWIE star showed off her washboard stomach on Instagram yesterday (5 March) along with her amazing golden tan.
Lucy has been working on her bod for a long time now and has set up her own fitness business, Results With Lucy, and even hosts her own 'BootyCamps'.
Sporting a gorgeous nautical navy and white striped bikini (which we really want), Lucy took the opportunity to flaunt the fruits of her labour in her racy iPhone snap.
She was also rocking a dove grey mani and a silver watch, wearing a bracelet and hair tie around her wrist.
And although Lucy only jetted in from Florida yesterday, she's already craving to go back, captioning her pic: "Wish I was putting this on today not a jumper take me back to Miami!!!!!"
We can't say we blame her, though. As well as lapping up the sun on a yacht, Lucy also went dolphin watching and even spotted Simon Cowell, his girlfriend Lauren Silverman and their new son Eric on the beach.
We're not surprised she wanted to stay longer!
