The 25-year-old met model Cara Delevingne inside the LOVE magazine party at private members’ club LouLous and the pair were spotted leaving together after the night out.
The duo were arm in arm as they headed towards their taxis. Cara, who had made a stylish appearance at Burberry earlier on in the day, wore a Burberry black lace skirt and a green quilter bomber jacket.
Eugenie, meanwhile, was decidedly more demure, sporting a black dress, with a black blazer and barely-there strappy heels.
At the party, the pair had rubbed shoulders with a host of fellow famous faces including Harry Styles, Daisy Lowe, Alexa Chung and Lily Allen.
It’s unknown how well Cara and Eugenie know each other, but Eugenie was reported to have invited Cara to her 25th birthday celebration back in May.
Earlier in the day, Cara put in a front row appearance at Burberry with her girlfriend St. Vincent. The couple put on a rare public display of affection as they enjoyed the show together alongside Sienna Miller and Kate Moss.
The pair looked at ease as they laughed and chatted ahead of the show with Sienna and Kate, and St. Vincent was also spotted making Cara laugh and smile as she whispered something in her ear.
Both stars looked as stylish as ever in all-black ensembles for the show, with Cara opting for a tailored blazer and trouser combo, while St. Vincent, whose real name is Annie Clark, wowed in a sleeveless black dress with cut-out detailing.
It’s not the first time they have hit the front row together – they also attended the British heritage brand’s show together earlier this year, held at the Griffith Observatory in Los Angeles.
