The reality TV star looked stunning in monochrome print trousers, silk black vest and black heels which showed off her Marbs tan and the results of her recent exercise regime.
Lucy enjoyed a night out at Funky Buddha nightclub in London's fashionable Mayfair.
She left alone, despite her recent holiday fling with handsome co-star Dan Osborne.
We last saw Lucy throwing a glass of red wine in the face of love rat ex-fiancé Mario Falcone in the last of two TOWIE Marbs specials.
But last night (June 7), she was drinking the wine not throwing it!
Co-star Chloe Sims was also out on Friday night, looking pretty in a loose-fitting black dress for a night at The Brompton Club.
With Chloe looking this hot, perhaps TOWIE's newest cast member Wayne Lineker might want to eat his words about her not being his type?
