What Is You Favorite Relationship Between A Male/Femail Castmember Together Of Screen?

Sorry, not understanding the question. Relationships between cast members OFF screen? Julia Roberts (who guest starred) and Matthew Perry. I don't know who else of the cast dated in real life.

I Mean Friendship

Oh okay... I'm not sure about that one, I've heard they all hang out together still but I only ever see Jennifer and Courteney together.
