The Only Way Is Essex star looked gorgeous in a monochrome dress that showcased her figure and highlighted her trim waist as she exited the Riverside Studios in London on Wednesday evening (28 August).
Lucy was also sporting a serious glow – no doubt thanks to her recent glamorous trip to sunny Los Angeles.
The 22-year-old has recorded a guest appearance on Celebrity Juice, telling her more than one million Twitter followers she'd had "the funniest night filming" alongside Holly Willoughby, Fearne Cotton and Keith Lemon.
And clearly she impressed Keith, who tweeted at her afterwards: "Lovely to see ya last night. Great sport. Glad you had fun x."
We haven't had Lucy on our screens since TOWIE wrapped its last season earlier this summer - and the episode will mark Fearne's return to Juice following her maternity leave - so we'll definitely be tuning in!
Not that Lucy hasn't been busy – since TOWIE went off air she's thrown herself into business ventures including her Lucy's Boutique store, a modelling assignment with Caprice and her Results With Lucy website, which offers fitness and nutrition advice.
A source has also told Reveal the brunette beauty could be expanding her profile outside the UK, saying her recent trip to LA included plenty of exciting business meetings.
Our insider told us not only did Lucy meet with a top film producer about a possible feature film role, she also conducted meetings about bringing Results With Lucy to the US.
"She's been inundated with American subscribers and is now in talks to bring RWL and a range of her own health products, to LA, where fitness is everything."
