Kareena's sister, Karisma Kapoor, replied "Can't waitttt." Gauri Khan, who is producing the film, wrote "It's going to be insane." Their replies added to fans' interest in a possible on-screen reunion.

A behind-the-scenes picture from a special song in which Kareena dances with Shah Rukh has been shared. The track is reportedly titled Daddy Cool and is composed by Sachin-Jigar. The release date of the song has not been announced.

The two last shared the screen in Ra.One in 2011. Earlier films they made together include Asoka (2001) and Kabhi Khushi Kabhie Gham... (2001).
