According to industry buzz, Siddarth and girl friend Soha Ali Khan have again had a major fight with Sid walking out of Soha's apartment.

Common friends reveal that the actor had moved in with Soha after buying her new pad in Bandra. In fact, whenever he's in town, he stays at Soha's place. According to sources it all began with a small argument.

Soha felt that Siddarth wasn't giving her enough time and attention. Since Siddarth refused to go public about their relationship, Soha is feeling stifled.

Siddarth is extremely moody and they often have fights. Soha loves to party and is an extrovert while Siddarth is a loner.

So this time, the fight got out of hand and Siddarth decided to move out. Siddarth shifted out a day before Saif's birthday party at Four Seasons.

Though both Siddarth and Soha came to the party together, he was very uncomfortable about getting his pictures clicked together with Soha and hid his face when the photogs tried to click them together.

Soha and Siddarth have had lot of fights in the past, but they haven't yet called it quits!
