Lucy, who quit TOWIE at the end of the last series, has been soaking up the sun in Florida for the past week and was pictured yesterday while with a friend onboard a yacht.
The brunette reality star showed off her washboard stomach (and is that a six pack we spy?!) in a nautical navy and white striped bikini.
Posting the holiday snap on Twitter, Lucy told her followers: "Day on the boat #Miami."
Last year, Lucy made it her mission to get in shape. She has also been helping fans get healthy after launching her own fitness website Results With Lucy and her boot camp Bootycamp With Lucy.
And just because she's on holiday, it doesn't mean that Lucy has thrown her exercise regime out of the window. The star also shared a snap of herself doing press-ups on a rock, saying: "You can do it anywhere girls!!!!"
No wonder she's got abs of steel!
Lucy is clearly having a great time in the US and, along with a spot of dolphin watching, she has also been doing some serious star spotting after clocking Simon Cowell, his girlfriend Lauren Silverman and their new baby son Eric on the beach!
Lucy also tweeted: "Just saw baby Eric he's sooooo cute!! #Miami."
