Preity Zinta spoke about her issue with Aishwarya Rai Bachchan, Kareena Kapoor Or Rani Mukerji. According to Preity Zinta Aishwarya's my favourite, because I did a world tour with her and enjoyed working with her. Also, I've worked with her for years, and we have a good equation, whether my film's a hit or flop, or whether hers becomes a hit or flop, nothing changes.
