Ae Dil Hai Mushkil's promotion spree refuses to end. The film and its cast is everywhere -- on TV shows, in colleges, at events and on magazine covers. But when we say film's cast, we mean Ranbir Kapoor, Anushka Sharma and director Karan Johar. One big star and may be the film's biggest attraction, Aishwarya Rai Bachchan has been missing from promotions. Even when the film had a special screening in Mumbai recently, everyone was there minus Aishwarya. The tongues, needless to say, started wagging.
