Shahid Kapur is back after a prolonged shoot abroad. And with his arrival, speculations about his split from girlfriend Kareena Kapoor [Images] are rife again.

Apparently, the split was caused not because of Saif Ali Khan [Images], who was rumoured to be dating Kareena, but because a certain actress has made inroads into Shahid's life.

The actress in question is on the thin side of slip, and still struggling to establish herself in the film industry.

According to a source, the actress met Shahid a month before he left for Canada [Images] and apparently, this episode left Kareena fuming.

Another incident that troubled Bebo was when this actress shifted her residence closer to Shahid's.

Shahid and Kareena have a movie coming up, on October 26 -- called Jab We Met. Ironically, events in their personal lives look like setting up the sequel -- Jab We Parted.
