But as they say, familiarity can also breed contempt.
Karan Mehra and Hina Khan, the lead pair of hit television show Yeh Rishta Kya Kehlata Hai, belong to the second category.
Despite playing on-screen lovers (Naitik Raj Singhania and Akshara) for the past six years, no sweetness has trickled down to their real-life rishta, say sources.
In fact, the cold war, which is as old as their reel pairing, is showing no signs of thawing.
This was evident yesterday, when Karan did not invite his leading lady for the launch of a song sung by his wife Nisha Rawal.
Maybe to show that Hina was not the only omission, he did not invite any of his co-stars either.
Nisha had recorded a cover version of AR Rahman's popular track 'Choti Si Asha'. She released it on the eve of Children's Day to raise funds for underprivileged children.
Interestingly, a few days ago, when we texted Hina and asked about her attending the event, she gave quite a telling reply: " So sorry, (I) have no idea about it."
Karan, on the other hand, did not revert at all.
Well, all we can say is, actions speak louder than words.
