Hrithik Roshan and Deepika Padukone will be seen sharing the screen for the first time in the upcoming movie `Fighter`. Directed by Siddharth Anand, the film will see the good-looking actors as Airforce officers. However, it seems like the duo instantly hit it off while making the film and a recent BTS pic is proof of the off-screen chemistry shared by the two. 

On Hrithik Roshan`s birthday on Wednesday, Deepika took to her Instagram stories to share an unseen picture from the sets of `Fighter` movie. In the picture, Deepika is seen having a slice of pizza when Hrithik attempts to block her from having it. Deepika is seen dressed in a casual black t-shirt while Hrithik is seen in a white t-shirt. There is a box of pizza in front of them with Deepika trying to eat one slice. The actress is also seen laughing while her co-star tries to stop her.
