While her former TOWIE co-stars were celebrating the end of another series, fitness fanatic Lucy was across town at the Give Me Sport launch party.
Lucy looked absolutely gorgeous in her floaty dress – perfect for summer nights! – that showed off her fabulous figure to best effect.
She was also sporting a very deep glow – the result of her recent holiday to Rome, perhaps?
It's no wonder Lucy is looking so healthy and great lately. Not only is she the proud owner of her own fitness and nutrition brand, Results With Lucy, but she's been hard at work in the gym every day preparing for her debut on BBC's Tumble.
The new Saturday night primetime show, which starts 9 August, challenges a group of celebrities to learn and then demonstrate a series of difficult gymnastics skills.
Eek! Nobody can say Lucy isn't up for a challenge, then!
Last month, Lucy, who has no formal gymnastics training, said: "I'm scared, nervous and more excited than I can describe about Tumble! To have the opportunity to learn a new skill is a dream come true for me. Although I'm sure I'll be falling over a lot before then!"
Other stars competing include Girls Aloud's Sarah Harding, Sugababe Amelle Berrabah, EastEnders' John Partridge and Andrea McLean.
