The certainty that nothing remains permanent in the Hindi film industry has just proved to be true.

One of the thickest links in Bollywood with flicks such as 'Main Hoo Na' and 'Om Shanti Om' being King Khan and Farah Khan has recently gone bitter. But what is the cause behind this legendary Khan break up?

The sources discovered the cause behind the split of this extraordinary pair.

As already known that Farah was keen on casting SRK in her forthcoming film 'Tees Maar Khan' but because the actor could not find enough time and Farah could not afford waiting forever lastly decided to cast Akki in the film.

It looks that this did not go down too well with Shahrukh and Farah had to bear the reverberations.

Farah went to SRK to make him receptive to her interest in remaking the old smash hit 'Satte Pe Satta' that failed to interest SRK. After hearing Farah for a moment, SRK at last said a firm 'no' to and showed his disinterest in the movie.

Farah had already approached Raj Sippy's son Mintoo to purchase the copyrights of the movie and he keenly accepted the offer. Shahrukh reasoned saying that he didn't wish to be a part of remake of Big B's flicks to which Farah retaliated saying that he had worked in the remake of 'Don'. Shahrukh did not really like this reaction and the chat ended coolly with Farah leaving his company.

He has also denied to do Shirish Kunder's movie and showed disinterest in 'The Zoya Factor'. This news will absolutely be disappointing for the viewers who loved watching the dynamic pair together! (With Inputs from Agencies)
