When you work on a movie with someone, you often times end up getting close to your co-stars (whether it's scripted or unscripted).
In the case of KJ Apa and Britt Robertson, they play each other's love interests in the film "I Still Believe" which is in theaters now.
It doesn't get much closer than that, so to put their knowledge to the test, BuzzFeed pulled the two theatrical love birds together to see how much they really know about each other.
It starts with BuzzFeed asking the young stars a question about their favorite craft service foods, and what they like to do between acting takes, which shouldn't be too hard to remember.
Then, they get into some more difficult, much more personal, questions like their favorite movie and what year they were born.
Though they start to feel the burn as the questions heat up, they're able to pull together some answers that are surprisingly close to the right answer...if not exactly right.
The chemistry between the two is obvious in "I Still Believe", but the segment definitely reinforces how strong their connection really is.
