Buzz is that Aishwarya Rai Bachchan, Ranbir Kapoor and Anushka Sharma will begin shooting for Karan Johar's 'Ae Dil Hai Mushkil' with a wedding number.

The shoot is apparently slated to begin next month. The movie will be filmed in London, Paris and Vienna.

Though Ash will be busy with the promotions of her comeback film, 'Jazbaa', she will take off for a few days for the song shoot.
