Katrina Kaif has come to the rescue of her good friend Salman Khan, stepping in as his leading lady in his upcoming Bollywood flick ‘Bharat’. Sallu’s earlier heroine, Priyanka Chopra, had quit the project last minute. Speculations suggest that PeeCee is tying the knot with her alleged beau Nick Jonas. Directed by Ali Abbas Zafar, ‘Bharat’ went on the floors a few weeks ago with Salman and Disha Patani shooting for circus sequences and a few stunts for the film. Katrina has worked with Salman in several films and the duo also earned a lot of praise at their recent Da-bangg tour.
