Despite their busy schedules, the duo seems to enjoy working together.
Katrina, who has turned out to be an avid social media user, shared an adorable picture of the duo from the sets of the movie on Instagram.
She captioned the snap, "No caption required @beingsalmankhan #tigerzindahai."
In the picture, while Salman Khan is seen hiding his face, Katrina seems to be smiling at his antics.
The two exes seem comfortable with each other and will be seen sharing screen space after five years.
' Tiger Zinda Hai' is a sequel to Kabir Khan's ' Ek Tha Tiger' which also starred Salman and Katrina.
Produced by Aditya Chopra under Yash Raj Films, the film is gearing up for Christmas release this year.
