Bombay Times published the first look of the pair in the film.
The film will see SRK working with Katrina Kaif for the first time on celluloid.
Anushka Sharma also features in the film,which is being shot extensively in London, followed by a long schedule in India.
Katrina and SRK were approached for many projects together in the past, but they chose this film because the story appealed to them.
The film will also see yet another pairing: AR Rahman and Gulzar.
Bagging this role was a big deal for Katrina, as Yash Chopra's penchant for projecting his heroines in a grand and elegant manner is the stuff Bollywood legends are made of (remember SIlsila).
The film is expected to release this Diwali.
