Do Ты have any idea if Neil and Cobie are Друзья in real life?

I mean, they clearly get along very well and have become awesome friends, but I was wondering whether they were meeting sometimes when they are not working on HIMYM или not. They always seem so familiar, just Поцелуи (I Любовь that Neil always kisses her on the mouth btw :D) and hugging all the time and so I found it strange that I never see any "paparazzi" pictures of them meeting for ужин или something. I've never seen any "off set" and "off the red carpet" pictures of any of those five together in general. Do Ты have any idea about that subject?
