"December 13 guys! Shooting for the last few days of 'Highway' in Delhi. Cannot believe this film is coming to an end. Now time for yoga. Thank you so much for all the amazing feedback on the recent stills of 'Highway'! It is a very special film to me hope you guys love it too," she tweeted.
'Highway' is set in six different states and captures the journey of two completely opposite people who are thrown together by fate.
