Mumbai: Saif Ali Khan and Kareena Kapoor have been together for almost four years now. The duo are reportedly passing through a rough patch as rumors about their strained relations and lack of trust start swirling thick and fast.

Sources close to the duo say that things are no longer rosy between the two actors who are no longer at the same professional level they used to be. Kareena, though is a lot more better and earns at least double the amount that she used to earn at the beginning of their romance, is facing stiff competition from newcomers and others including Deepika Padukone, Katrina Kaif and Sonam Kapoor.
