The former TOWIE star, 23, was pictured looking svelte and chic in her Ellesse gym gear as she walked through London on Thursday (25 June).
Lucy's been the face of Ellesse since last year.
She's a natural fit to promote the sports brand considering her massive success with fitness and nutition brand Results With Lucy.
In just 24 months the company has gone from strength to strength, offering a variety of different workouts, recipes, nutrition and health tips and more via its website and accompanying book, Be Body Beautiful, as well as BootyCamps attended by Lucy herself.
Lucy celebrated two years of success on Wednesday evening, slipping into a pretty maxi dress to toast the company with champagne during a summer garden party.
She told Essex Style Magazine earlier this year:
"Results with Lucy is an online fitness and nutritional programme, it offers various workouts from beginners to advanced doing anything from dance to yoga. They are all available to download and use in the comfort of your home so there are no scary gyms involved!
"It also means you can get fit at any time of day and fit it around your daily schedule. I came up with concept after tweeting workout videos with my personal trainer Cecilia Harris and my followers asked how they could join in too."
