Meanwhile, Ansel previously admitted that he uses his social media accounts to further his acting career.

The 'Baby Driver' star also revealed he hopes to be a positive influence on young people through his online presence.

He said: "I mean, that's why I'm on social media, that's why I am active on the internet because I think it's beneficial to someone's career.

"But also I have an audience and I think I have taken this role, whether I like it or not, as an influencer and I want to be a positive influencer. I want to encourage people. One of the things I do encourage people is that that internet is a place where we should share our ideas and be positive, not negative."
