Lottie, meanwhile, was pictured at the PrettyLittleThing party. The model wore a brown denim dress and a leather jacket with fluffy trim.

Bystanders told MailOnline how Leo and Lottie sat together in the Chiltern Firehouse before leaving early on Wednesday morning.

One partygoer said: ‘You’ve got Leonardo and Lottie in the same room, of course they gravitated towards each other.

‘They were chatting and giggling until the early hours when it was time to end it. They left the club in the early hours after having a great time.

“It got people talking, they’re both celebrities having a good time.”

A source told The Sun: ‘Leo and Lottie had a great time and seemed very close.

‘They arrived separately, but within a few minutes of each other, and sat at the table with other friends.

‘Their closeness raised a lot of eyebrows – and people in the club were talking about Kate, and also the fact that Lottie seems to be in the right age range for Leo.’

Leo traveled to the French capital after partying until the early hours with Lottie, 25, at London’s Chiltern Firehouse on Wednesday morning – 30 years after he dated her sister Kate, 49.

Earlier in the evening, Leo attended a special screening of his latest blockbuster Killers Of The Flower Moon at the East Room in London with his co-star Lily Gladstone.

He later headed to Chiltern Firehouse – a restaurant and late night bar popular with A-listers like Bella Hadid, Joan Collins, Dua Lipa, Mark Ronson, Winnie Harlow and Noel Gallagher – wearing the same black button-up jacket and a matching sweatshirt .

The actor arrived first before Lottie, who arrived slightly later than the Hollywood star.

Lottie partying with DiCaprio will likely alarm her older sister Kate, who dated him 30 years ago. Lottie wasn’t even born yet when the two stars had a brief affair in December 1993, shortly before she started dating Johnny Depp.

The pair met as young models in the US when they were teenagers and although they spent a lot of time together, it is believed their romance was short-lived.

On her Instagram on Wednesday, Lottie posted photos of herself wearing new hair extensions that she thought she had done before her night with DiCaprio.

On Tuesday evening she also celebrated her birthday with her model friend Aine Sweeney Byrne.
