Do আপনি have any idea if Neil and Cobie are বন্ধু 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 অথবা not. They always seem so familiar, just স্নেহ চুম্বন (I প্রণয় 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 ডিনার অথবা something. I've never seen any "off set" and "off the red carpet" pictures of any of those five together in general. Do আপনি have any idea about that subject?
