Kareena, Shahid Heading for a Split?

The chhote nawab strikes again. If sources are to be believed then Kareena Kapoor has put her three-year-old relationship with Shahid Kapur on line for the super charming Saif Ali Khan.

If sources are to believed, then it's all over between Kareena and Shahid. The couple, who was being seen as the one that is most likely to stick with each other, has reportedly split. And the split is because of the entry of a third person, namely Saif, into the relationship. Bebo and Saif are behaving like teenagers in love and are constantly sending each other messages and even have photos of each other on their phone. However, Kareena is still a little wary as Saif is known to be commitment phobic. The couple came close while shooting for Yash Raj Film's Tashan. As for Shahid, he is in Canada shooting for Nagesh Kuknoor's Tasveer. So he is quite clueless about what is happening on the Kareena-Saif front. The couple has been having problems for a while now. The question that arises is how serious is Saif? Ever since he split with Amrita Singh and Rozza, he seems to be just in the mood for some more excitement. Is it a case of exit Bipasha and enter Kareena?
