Lucy was spotted at an art gallery in the capital on Thursday evening (16 January), checking out an exhibition by artist Russell Marshall, which was held in celebration of British icon Kate turning 40 years old.
So it's no wonder that Lucy - who has also dabbled in modelling recently - wanted to keep things classy for the evening by channeling her idol in an all-black ensemble.
Taking inspiration from Kate's love of skinny jeans and blazers, Lucy wore a pair of skin-tight trousers and a long jacket from Bershka and teamed them with a plain, loose-fitting grey T-shirt.
She completed her chic look with some statement cutout heels from United Nude and a vintage Chanel handbag, while leaving her long brown locks slightly tousled.
Clearly the reality star was impressed with the exhibition, as she and her pal posed for a photo next to one of the pictures of Kate and claimed that they were "appreciating the face".
Lucy and the rest of her Made In Chelsea co-stars are currently on a break from filming their hit E4 series and are no doubt welcoming a bit of peace and quiet following the drama that ensued at the end of last year.
Before Christmas, Lucy was seen admitting her feelings for Jamie Laing on the show and then riding off into the night with him in a horse-drawn carriage.
But although the pair clearly had a spark between them, Lucy later revealed that she still couldn't trust Jamie and his flirty ways, so they decided to remain just friends.
Meanwhile, her BFF Binky Felstead has been a bit more lucky in love and jetted off on a romantic trip to India with co-star and boyfriend Alex Mytton earlier this month.
