“It got people talking, they’re both celebrities who like to have a good time.”

Earlier in the evening, DiCaprio, 49, attended a special screening of his latest blockbuster Killers of the Flower Moon at the East Hall in London along with his co-star Lily Gladstone.

He later went to the Chiltern Firehouse – a restaurant and late-night bar popular with celebrities such as Bella Hadid, Joan Collins, Dua Lipa, Mark Ronson, Winnie Harlow and Noel Gallagher – wearing the same black button-down jacket and matching sweatshirt.

The actor arrived first ahead of 25-year-old Lottie, who arrived a little later than the Hollywood star.

Lottie’s party with DiCaprio is likely to alarm her older sister Kate, who dated him 30 years ago. Lottie was not yet born when the two stars had a brief fling in December 1993, shortly before she dated Johnny Depp.

The couple met each other as young models in the US when they were teenagers, and although they spent a lot of time together, their romance is believed to be short-lived.

Taking to Instagram on Wednesday, Lottie posted photos of herself getting new hair extensions, which she was believed to have gotten ahead of her evening with DiCaprio.

She also celebrated her birthday with her model friend Aine Sweeney Byrne on Tuesday night.

Lottie's party with DiCaprio will likely alarm her older sister Kate, who dated him during a brief fling back in 1993.
