Leo and Camila were first linked in late 2017 and have been together ever since.

At the time, Us Weekly reported the couple were ‘hooking up.’

Obviously, the relationship has grown progressively more and more serious since then.

Walk and talk: DiCaprio listened to his girlfriend as they continued with their conversation

‘They seem pretty serious,’ an insider told People in 2019. ‘It’s definitely not a casual relationship. Camila spends a lot of time at his house.’

The couple have been spending even more time together in lockdown.

A source told People in June: ‘He is usually very independent, spends lots of time with friends, but because of the lockdown, he has mostly spent time with Camila. He loves being with her.’

Throughout their three year relationship, the couple have faced criticism over their 22 year age difference, with DiCaprio known for dating women in her age group.

Camila, however, isn’t bothered by the backlash.

‘There’s so many relationships in Hollywood — and in the history of the world — where people have large age gaps. I just think anyone should be able to date who they want to date,’ she previously told the Los Angeles Times.

Speaking up: As Camila pursues a career in acting, however, she admitted it can be ‘frustrating’ constantly being linked to her famous beau

As Camila pursues a career in acting, however, she admitted it can be ‘frustrating’ constantly being linked to her famous beau.

However, she believes this will be less of an issue as she continues to forge a career in film.

‘I think more and more now that people are seeing the film, I’m slowly getting an identity outside of that,’ Camila said while promoting her 2019 movie Mickey and the Bear.

‘Which is frustrating, because I feel like there should always be an identity besides who you’re dating… I understand the association, but I’m confident that will continue to slip away and be less of a conversation.’
