The models both chose all black outfits on Monday (23 February) for an evening at Edition Hotel and then celebrity haunt Mahiki Club, following a day spent at London Fashion Week.
They held hands as they battled the cameras outside Mahiki.
Kendall, 19, had been walking in the Giles show at LFW earlier in the day, while Cara, 22, was in the FROW to support her bestie.
Keeping Up With The Kardashians star Kendall and Cara have been inseparable over the last few days, attending shows together including Topshop Unique, and hanging out away from the catwalk.
Over the weekend, they added Jourdan Dunn and Kate Moss to their group, sharing a models-only dinner at the exclusive Mr Chow restaurant in Knightsbridge.
They both jetted into London from New York Fashion Week, where Kendall appeared to be the most in-demand model around with appearances on a slew of top runways including Marc Jacobs and Vera Wang.
