The former TOWIE star is currently celebrating a friend's hen party in America's sin city, Las Vegas, and finding lots of opportunities to show off THAT amazing body.
On Friday, fitness fanatic Lucy shared a jaw-dropping selfie from her hotel room.
Despite wearing a black bikini with a gorgeously-adorned neckline, it's Lucy's awesome abs that steal the limelight.
She's tanned, toned and totally tantalising...
So it's no surprise that when Lucy found herself at a pool party with US R&B singer Ne-Yo, he seemed to take rather a shine to her!
Posing in a picture together, Ne-Yo looks like the cat that's got the cream and has his arm wrapped around Lucy's teeny waist.
Sharing the picture with her Twitter followers, Lucy wrote: "Normal day!! #vegas #HelloNeyo."
One fan spoke for all of us when she said: "SO F***ING JEL GIRLS."
