The Swiss Army Man actor previously explained that he and Erin work so well together because they are best friends. 

He told Us Weekly: "I think that's the kind of relationship I always aspire to have with someone I'm in a relationship with. You want that person to be your best friend. 

"In the case of Erin, we definitely are."                       

Daniel also discussed his approach to relationships and the world of modern dating. 

He said: "I don't think you can ever control how anything starts. 

"It's not like I seek out that way of meeting people or think I have to be their friend first but I think it's often a very natural thing to progress from into a relationship. The whole modern idea of 'friend zone' and all that stuff - that's a word I don't like very much."
