Karan Johar was spotted yesterday afternoon at the Gateway of India. The filmmaker had turned tourist photographer for the upcoming TV show, Mission Sapne.

Several B-Town folk feature in it to help raise funds for a common man facing adversity in his life.

The money KJo earns by shooting pictures of tourists will be multiplied and given to tourist photographer Hemant Das who has been struggling to support his family as his wife needs urgent medical attention. Other B-Town stars who are part of the show include Salman Khan and Sidharth Malhotra.
