I hear Karan Johar after wrapping up the shoot of 'Ae Dil Hai Mushkil' with Ranbir Kapoor and Anushka Sharma in London tomorrow, will head to Lucknow immediately for a few days with his unit.

The filmmaker is keen to include a few scenes against a winter backdrop before the crew goes on a break before the New Year. His film also stars Aishwarya Rai Bachchan, in what will be an unusual love triangle.
