But there have been unusual friendships too, like between the likes of Sallu-Aamir and Akshay-Aamir.
Now the buzz is that Shah Rukh Khan and Hrithik Roshan have been bonding big time.
The actors who played brothers might have had some problems while making the ‘Krazzy 4' song but that's a thing of the past now.
The 'Jodhaa Akbar' actor and King Khan have been catching up a lot these days.
Hrithik is a permanent fixture at Mannat and he and wife Sussanne have been at most parties at King Khan's home.
Not only that, they even partied together when they were in Dubai last year for the opening of Atlantis. SRK was at Roshan Jr's home a few nights ago.
A source said, "It was no occasion as such, just a casual affair. SRK was there for quite a while. Later in the night, the host and the guests decided to play dumb charades of Hollywood flicks. The guests were divided into two teams of Hrithik and Shah Rukh. Both sides did their bit of miming and SRK's team was declared to be the winner."
They manage to keep the dosti going in spite of their busy schedules.
The source added, "Though Hrithik is extremely busy with his home production Kites, he is still taking time out to catch up with SRK. A few weeks ago, the duo was even spotted chilling out together."But this is not the first time that the two have bonded. It has happened in the past too.
"In 2006 when ‘Krrish' had released, Hrithik had a special screening for Shah Rukh to garner his frank opinion. Later, when Hrithik was in London to promote the film, SRK (who was holidaying there) had hosted a special dinner for him.
B-Town is slowly getting a whiff of the SRK-Hrithik bonding. Both stars refrain from talking about each other. Hrithik is known for being extremely guarded while SRK has not yet given his reply to Aamir's recent outbursts against him."
This sure is one special yaari. We just hope it stands the test of time, unlike all other crumbling friendships in B-Town.
