Salman invited him to his party and kushal obliged by going!! Doesnt anybody think that if kushal had declined the invite, itwould have been too rude? Salman khan is a powerful man and no doubt one of the most respected in the industry!!
It is actually a good move on both the parties part!!
In all this i remember one of kamya's saying in the show where she said ki yaha se nikalkar sab ek dusre se ache se hi milenge!
