Who wants Saif and Kareena to split?

According to sources, Saif Ali Khan suspects that some unwanted elements are trying to create a rift between him and his lady love, Kareena Kapoor.

Saif apparently feels that some people are trying to feed friends and the media with negative stories about their romance and this leads to various stories about their love tiffs.

A friend of the couple says, "When Saif and Kareena hear about their so-called fights now and then, it obviously bothers them. They think that someone is trying to meddle in their personal and professional lives. Kareena wants to get to the bottom of the matter and find out who exactly is the culprit." She has apparently asked her manager to investigate who exactly is behind the smear campaign.

Earlier stories have circulated that Saif-Kareena were having constant fights - incidents had been reported on the sets of Kareenas films and even once inside her vanity van. Also, it was reported that Kareena, tired of Saifs possessive ways, was trying to end their relationship.

The friend continues, "Kareena reacted strongly when it was reported that she has been replaced by Deepika Padukone in Saifs next home production Agent Vinod, directed by Sriram Raghavan. Kareena was very upset over the issue."

Saif, when contacted, admits that he is upset over constant rumours being floated about him and Kareena. "I dont know whether these rumours come from. Non-issues are made into issues. They are so baseless," says Saif.

According to Saif, the rumour of Kareena getting replaced by Deepika was floated at a time when Kareena hadnt even heard the script of Agent Vinod. "It was always going to be Kareena in my film provided she wants to do it of course. In fact the script still hasnt been narrated to her," Saif says.

Saif, sources say, sniffs business rivalry. "Saif is worried that his business rivals are trying these subversive techniques to stab him in the back and sour his relationship with Kareena. They dont know that the understanding between them is very strong," the close friend adds.
