Salman Khan and Katrina Kaif were supposed to perform together on their popular onscreen chartbusters at a superstar night show in Chicago. The event was initially scheduled for September, but now it's been called off, for the reasons best known to both the stars.

It is being said that Salman is quite miffed with the recent leaked bikini pictures of her ex-girlfriend Katrina Kaif's with Ranbir Kapoor, and thus decided not to perform with her. However, sources close to the actors are citing some other reasons for this sudden called-off.

According to sources, as Salman's UK visa was being delayed, his entire work schedule went for a toss. And thus it was quite difficult for him to accommodate a stage concert show in the middle of his shooting. Meanwhile, Katrina is also busy with her several endorsement shoots in India and overseas.

Well, seems like something is definitely wrong between the ex-lovers turned good friends.
