Priyanka Chopra having problems with Salman Khan?

Priyanka Chopra and Salman Khan were good friends and even acted opposite each other in Mujhse Shaadi Karogi and Salaam-e-Ishq . But now reports are that all is not well between the two ever since Salman made demands to replace Priyanka with his girlfriend Katrina Kaif in London Dreams .After that things soured between Priyanka and Salman, recently things were just returning to cordial between the two of them. But recently Sohail Khan offered Priyanka a role opposite himself in his co-production 'Mr. and Mrs. Khanna', but Priyanka refused. A source claims "Sohail directly offered the part to Priyanka, but she refused it as she wanted to act opposite a bigger star."Moreover 'Mr. and Mrs. Khanna' also stars Salman and Lara Dutta , so if Priyanka is paired opposite Sohail, she will definitely be overshadowed.
