They have a pretty good friendship. आप can see it, they have a laugh together during interviews & little innocent flirty remarks but that’s totally pure. They also have a laugh together on twitter. I प्यार them as friends, they both claim not to "Ever तारीख, दिनांक a co-star". So no chance of 'Nian' happening. And Ian is in a relationship with a woman named Megan, and he refers her as his "Pretty lady" xD. Nina & Ian are really good friends, let’s leave it at that.
