It seems like Leonardo DiCaprio is not single anymore. The Revenant star has reportedly been "regularly flying" to the UK to meet his rumoured girlfriend, model Roxy Horner.

The model and the 41-year-old Oscar winner were spotted enjoying each other's company when they visited Tapas restaurant and later at the Chiltern Firehouse in London on 31 May (Tuesday).

"Leo didn't leave Roxy's side. After the club, they headed down to the Chiltern, where a number of onlookers said the pair looked extremely cosy together," a source told The Sun.

"Roxy is a really sweet, caring normal girl. She's naturally stunning and she has a lot in common with Leo. They're smitten and enjoy spending time together," the source added.

In January this year, DiCaprio was linked to Rihanna after the two were allegedly spotted kissing by an eyewitness. In April, the two were spotted getting cosy at the Neon Carnival in California. However, the two neither confirmed nor denied their relationship.

Later that month, DiCaprio opened up about his thoughts on marriage during an interview with Parade magazine. "That time will come when that time comes. The truth is, you can't predict marriage. You can't plan it. It's just going to happen when it happens," he said.

"If I wanted to quit acting, I could have done it a long time ago. I love making movies. I feel lucky and fortunate to do it, and it is absolutely worth sacrificing a lot of my private life," he added.
